  text: Power semiconductor modules are used to control and switch high electrical
    currents and voltages. Within the power module package wire bonding is used as
    an interconnection technology. In recent years, aluminum wire has been used preferably,
    but an ever-growing market of powerful and efficient power modules requires a
    material with better mechanical and electrical properties. For this reason, a
    technology change from aluminum to copper is indispensable. However, the copper
    wire bonding process reacts more sensitive to parameter changes. This makes manufacturing
    reliable copper bond connections a challenging task. The aim of the BMBF funded
    project Itsowl-InCuB is the development of self-optimizing techniques to enable
    the reliable production of copper bond connections under varying conditions. A
    model of the process is essential to achieve this aim. This model needs to include
    the dynamic elasto-plastic deformation, the ultrasonic softening effect and the
    proceeding adhesion between wire and substrate. This paper focusses on the pre-deformation
    process. In the touchdown phase, the wire is pressed into the V-groove of the
    tool and a small initial contact area between wire and substrate arise. The local
    characteristics of the material change abruptly because of the cold forming. Consequently,
    the pre-deformation has a strong effect on the joining process. In [1], a pre-cleaning
    effect during the touchdown process of aluminum wires by cracking of oxide layers
    was presented. These interactions of the process parameters are still largely
    unknown for copper. In a first step, this paper validates the importance of modeling
    the pre-deformation by showing its impact on the wire deformation characteristic
    experimentally. Creating cross-section views of pre-deformed copper wires has
    shown a low deformation degree compared to aluminum. By using a digital microscope
    and a scanning confocal microscope an analysis about the contact areas and penetration
    depths after touchdown has been made. Additionally, it has to be taken into account
    that the dynamical touchdown force depends on the touchdown speed and the touchdown
    force set in the bonding machine. In order to measure the overshoot in the force
    signals, a strain gauge sensor has been used. Subsequently, the affecting factors
    have been interpreted independently Furthermore, the material properties of copper
    wire have been investigated with tensile tests and hardness measurements. In a
    second step, the paper presents finite element models of the touchdown process
    for source and destination bonds. These models take the measured overshoot in
    the touchdown forces into account. A multi-linear, isotropic material model has
    been selected to map the material properties of the copper. A validation of the
    model with the experimental determined contact areas, normal pressures and penetration
    depths reveals the high model quality. Thus, the simulation is able to calculate
    and visualize the three dimensional pre-deformation with an integrated material
    parameter of the wire if the touchdown parameters of the bonding machine are known.
    Based on the calculated deformation degrees of wire and substrate, it is probably
    possible to investigate the effect of the pre-deformation on the pre-cleaning
    phase in the copper wire bonding.

  text: In power electronics, ultrasonic wire bonding is used to connect the electrical
    terminals of power modules. To implement a self-optimization technique for ultrasonic
    wire bonding machines, a model of the process is essential. This model needs to
    include the so called ultrasonic softening effect. It is a key effect within the
    wire bonding process primarily enabling the robust interconnection between the
    wire and a substrate. However, the physical modeling of the ultrasonic softening
    effect is notoriously difficult because of its highly non-linear character and
    the absence of a proper measurement method. In a first step, this paper validates
    the importance of modeling the ultrasonic softening by showing its impact on the
    wire deformation characteristic experimentally. In a second step, the paper presents
    a data-driven model of the ultrasonic softening effect which is constructed from
    data using machine learning techniques. A typical caveat of data-driven modeling
    is the need for training data that cover the considered domain of process parameters
    in order to achieve accurate generalization of the trained model to new process
    configurations. In practice, however, the space of process parameters can only
    be sampled sparsely. In this paper, a novel technique is applied which enables
    the integration of prior knowledge about the process into the datadriven modeling
    process. It turns out that this approach results in accurate generalization of
    the data-driven model to unseen process parameters from sparse data.

  text: Self-optimizing mechatronic systems allow the adaptation of the system’s behavior
    to the current situation. This can be used to actively adapt the behavior to the
    current degradation state of the system or of some of its components. To this
    end, the Multi-Level Dependability Concept has been developed. In this contribution,
    we show how the Multi-Level Dependability Concept has been applied to the active
    suspension module of an innovative rail-bound vehicle. For this module, the usage
    of control reconfiguration, which is a novel approach to exploit complex redundancy
    systems, is required. We show that by combining self-optimization with the possibilities
    given by control reconfiguration, the dependability of a complex mechatronic system
    can be greatly improved.

  text: Recently, focus on maintenance strategies has been shifted towards prognostic
    health management (PHM) and a number of state of the art algorithms based on data-driven
    prognostics have been developed to predict the health states of degrading components
    based on sensory data. Amongst these algorithms, Multiclass Support Vector Machines
    (MC-SVM) has gained popularity due to its relatively high classification accuracy,
    ability to classify multiple patterns and capability to handle noisy /incomplete
    data. However, its application is limited by the difficulty in determining the
    required kernel function and penalty parameters. To address this problem, this
    paper proposes a hybrid differential evolution -- particle swarm optimization
    (DE-PSO) algorithm to optimize the MC-SVM kernel function and penalty parameters.
    The differential algorithm (DE) obtains the search limit for the SVM parameters,
    while the particle swarm optimization algorithm (PSO) determines the global optimum
    parameters for a given training data set. Since degrading machinery components
    display several degradation stages in their lifetime, the MC-SVM trained with
    optimum parameters are used to estimate the health states of a degrading machinery
    component, from which the remaining useful life (RUL) is predicted. This method
    improves the classification accuracy of MC-SVM in predicting the health states
    of a machinery component and consequently increases the accuracy of RUL predictions.
    The feasibility of the method is validated using bearing prognostic run-to-failure
    data obtained from NASA public data repository. A comparative study between MC-SVM
    with parameters obtained using simple grid search with n-fold cross validation
    and MCSVM with DE-PSO based on prognostic performance metrics reveals that the
    proposed method has better performance, with all the cases considered falling
    within a 10 \% error margin. The method also outperforms other soft computing
    methods proposed in literature.

  text: This study presents the methods employed by a team from the department of
    Mechatronics and Dynamics at the University of Paderborn, Germany for the 2013
    PHM data challenge. The focus of the challenge was on maintenance action recommendation
    for an industrial machinery based on remote monitoring and diagnosis. Since an
    ensemble of data driven methods has been considered as the state of the art approach
    in diagnosis and prognosis, the first approach was to evaluate the performance
    of an ensemble of data driven methods using the parametric data as input and problems
    (recommended maintenance action) as the output. Due to close correlation of parametric
    data of different problems, this approach produced high misclassification rate.
    Event-based decision trees were then constructed to identify problems associated
    with particular events. To distinguish between problems associated with events
    that appeared in multiple problems, support vector machine (SVM) with parameters
    optimally tuned using particle swarm optimization (PSO) was employed. Parametric
    data was used as the input to the SVM algorithm and majority voting was employed
    to determine the final decision for cases with multiple events. A total of 165
    SVM models were constructed. This approach improved the overall score from 21
    to 48. The method was further enhanced by employing an ensemble of three data
    driven methods, that is, SVM, random forests (RF) and bagged trees (BT), to build
    the event based models. With this approach, a score of 51 was obtained . The results
    demonstrate that the proposed event based method can be effective in maintenance
    action recommendation based on events codes and parametric data acquired remotely
    from an industrial equipment.

  text: In this contribution, we introduce a multiobjective optimization used to calculate
    safe optimal working points for a mechatronic system by including stochastic safety-critical
    signals in an objective function. Our application example consists of a linear
    drive for a rail-bound vehicle and an actuation unit. The linear drive's secondary
    part is fixed; the primary part is vehicle-mounted and can be adjusted vertically
    to account for deviations of the height of the secondary part. A small air gap
    between both parts improves efficiency, but increases the risk of a collision
    between the two parts. Using height data of the secondary part, a trajectory for
    the vertical adjustment of the primary part is calculated. However, unexpected
    deviations necessitate a readjustment of the air gap. The probability of such
    unexpected height deviations can be calculated from the readjustment data. The
    system is equipped with sensors to measure the air gap. Assuming that the sensor
    noise is normally distributed, noise characteristics are determined. Using this
    information and the probability distribution of unexpected height deviations,
    the probability of a collision is determined.T he sensor noise and the probability
    of a collision between both parts of the linear drive are included in the dynamical
    model of the system. Using multiobjective optimization, pareto-optimal working
    points for the controller of the air gap are obtained. By selecting an appropriate
    working point, safe operation can be ensured.

  text: Self-optimizing mechatronic systems allow the adaptation of the system's behavior
    to the current situation. This can be used to actively adapt the behavior to the
    current degradation state of the system or of some of its components. To this
    end, the Multi-Level Dependability Concept has been developed. In this contribution,
    we show how the Multi-Level Dependability Concept has been applied to the active
    suspension module of an innovative rail-bound vehicle. For this module, the usage
    of control reconfiguration, which is a novel approach to exploit complex redundancy
    systems, is required. We show that by combining self-optimization with the possibilities
    given by control reconfiguration, the dependability of a complex mechatronic system
    can be greatly improved.

  text: Self-optimizing mechatronic systems offer possibilities well beyond those
    of traditional mechatronic systems. Among these is the adaptation of the system
    behavior to the current situation. To do so, they are able to choose from different
    working points, which are pre-calculated using multiobjective optimization and
    are thus Pareto-optimal with regard to the chosen objective functions. In this
    contribution, a method is presented that allows to continuously control the system
    degradation by adapting the behavior of a selfoptimizing system throughout its
    complete lifetime. The current remaining useful lifetime is estimated and then
    related to the spent lifetime and the desired useful lifetime. Using this information,
    a reliability-related objective is prioritized using a closed-loop control, which
    in turn is used to determine the working point of the self-optimizing system.
    This way, the desired useful lifetime can be achieved. To exemplify the setup
    of the controller structure and to demonstrate the adaptation of the system behavior,
    a dynamic model of a clutch system is used. It can be seen that the closed loop
    controller is able to correct for external perturbations, such as changed requirements,
    as well as changed system parameters. This way, the modeled system is able to
    achieve the desired lifetime reliably.

  text: Selbstoptimierende mechatronische Systeme bieten die Möglichkeit, ihr Verhalten
    an geänderte Umgebungsbedingungen anzupassen. Dazu werden beispielsweise redundante
    Strukturen genutzt, Reglerparameter angepasst oder Regelstrategien umgeschaltet.
    Dies kann auch genutzt werden, um die Zuverlässigkeit des Systems zu steigern.
    Zugleich entstehen aber durch die gesteigerte Komplexität dieser Systeme zusätzliche
    Risiken. Um sicherzustellen, dass das System dennoch die gestellten Anforderungen
    bezüglich der Zuverlässigkeit erfüllt, ist eine Modellierung des Gesamtsystems
    und anschließende Zuverlässigkeitsbewertung notwendig. Dies ist aufgrund der situationsabhängigen
    Verhaltensanpassung und des nicht intuitiv vorhersehbaren Verhaltens jedoch nicht
    mit klassischen Verfahren möglich. Ein Modellierungsverfahren, das diese Eigenschaften
    abbilden kann, ist LARES (LAnguage for REconfigurable dependable Systems). Die
    Anwendung von LARES zur Bewertung der Zuverlässigkeit eines selbstoptimierenden
    Systems wird anhand des Feder-Neige-Moduls gezeigt. Es ist eine Baugruppe der
    Fahrzeuge eines innovativen Bahnsystems, der RailCabs. Das Feder-Neige-Modul dient
    dazu, unerwünschte Schwingungen des Fahrzeugaufbaus zu minimieren. Mit LARES können
    die Hardware-Komponenten des Systems, ihre in Abhängigkeit von der aktuellen Situation
    veränderten Belastungen sowie die nicht-deterministische Verhaltensadaption modelliert
    werden.

  text: 'The rapid development of communication and information technology opens up
    fascinating perspectives, which go far beyond the state of the art in mechatronics:
    mechatronic systems with inherent partial intelligence. These so called self-optimizing
    systems adapt their objectives and behavior autonomously and flexibly to changing
    operating conditions. On the one hand, securing the dependability of such systems
    is challenging due to their complexity and non-deterministic behavior. On the
    other hand, self-optimization can be used to increase the dependability of the
    system during its operation. However, it has to be ensured, that the self-optimization
    works dependable itself. To cope with these challenges, the multi-level dependability
    concept was developed. It enables predictive condition monitoring, influences
    the objectives of the system and determines suitable means to improve the system''s
    dependability during its operation. In this contribution we introduce a procedure
    for the conceptual design of an advanced condition monitoring based on the system''s
    principle solution. The principle solution describes the principal operation mode
    of the system and its desired behavior. It is modeled using the specification
    technique for the domain-spanning description of the principle solution of a self-optimizing
    system and consists of a coherent system of eight partial models (e.g. requirements,
    active structure, system of objectives, behavior, etc.). The partial models are
    analyzed separately in order to derive the components of the multi-level dependability
    concept. In particular, the reliability analysis of the partial model active structure
    is performed to identify the system elements to be monitored and parameters to
    be measured. The principle solution is extended accordingly: e.g. with system
    elements required for the realization of the dependability concept. The advantages
    of the method are shown on the self-optimizing guidance module of a railroad vehicle.'
