  text: Incremental nonlinear dynamic inversion (INDI) is a widely used approach to
    controlling UAVs with highly nonlinear dynamics. One key element of INDI-based
    controllers is the control allocation realizing pseudo controls using available
    actuators. However, the tracking of commanded pseudo controls is not the only
    objective considered during control allocation. Since the approach only works
    locally due to linearization and the solution is often ambiguous, additional aspects
    like control efforts or penalizing the deviation of certain states must be considered.
    Conducting the control allocation by solving a quadratic program this results
    in a considerable number of weighting parameters, which must be tuned during control
    design. Currently, this is conducted manually and is therefore time consuming.
    An automated approach for tuning these parameters is therefore highly beneficial.
    Thus, this paper presents and evaluates a model-based approach automatically tuning
    the control allocation parameters of a tiltrotor VTOL using an optimization algorithm.
    This optimization algorithm searches for optimal parameters minimizing a cost
    functional that reflects the design target. This cost functional is calculated
    based on a test mission for the VTOL which is conducted within a simulation environment.
    The test mission represents the common operating range of the VTOL. The simulation
    environment consists of an aircraft model as well as a model of the INDI-based
    controller which is dependent on the control allocation parameters. On this basis,
    model-based optimization is conducted and the optimal parameters are identified.
    Finally, successful real-world tests on a 4-degrees-of-freedom testbench using
    the identified parameters are presented. Since the control allocation parameters
    can significantly influence the aircraft’s stability, the 4-DOF testbench for
    the aircraft is required for rapid validation of the parameters at a minimum amount
    of risk.

  text: Manufacturing processes benefit from property control enabling reproducibility,
    application oriented outcomes, and efficient part production. In reverse flow
    forming, state of the art practices focus primarily on geometry control, neglecting
    property control. Given the intricacies of the process involving the interaction
    of tool and machine behavior, process parameters, properties of semi finished
    products and temperatures, incorporating process control becomes an imperative
    for producing components with predefined properties. The property controlled within
    this reverse flow forming process is the local α’ martensite content. Therefore,
    process strategies to actively influence the α’ martensite content must be implemented.
    In this study seamless AISI 304L steel tubes are used, where α’ martensite formation
    is strain  and/or temperature induced through phase transformation within the
    process. This paper presents innovative process strategies, methods, and specially
    developed mechanical and thermal actuator systems to locally increase or suppress
    the α’ martensite content. The use and implementation of these approaches and
    tools allows the creation of unique optically invisible microstructure profiles
    containing 3D gradings, implying a radial grading of α’ martensite. The locally
    implemented α’ martensite, forming these 3D gradings, offers potential applications
    for functional or sensory purposes. This paper extends beyond theoretical concepts,
    providing tangible component outcomes.

  text: Increasing the sustainability and resource efficiency of forming processes
    is one of today's major goals. High-strength wire materials are usually available
    as strip material and are subjected to a downstream forming process such as punch-bending
    to produce parts for the electronics industry, for example. During the manufacturing
    process of the semi-finished product, residual stresses and plastic deformations
    are introduced into the wire by rolling and drawing processes. Straightening machines
    are used in the production lines to compensate for these. To increase the sustainability
    of these production lines, the straightening process is an essential step. Before
    the continuous manufacturing process starts, the straightening process must be
    set up and the optimal roller positions must be found. Once the process is set
    up, the roller position settings are usually not changed. Due to missing measurement
    systems for the straightening quality, it is not possible to dynamically adjust
    the positions of the straightening rollers to variations in the material properties.
    This leads to deviations in the dimensional accuracy of the components to be produced
    and thus to an increase in the rejection rate in the manufacturing processes.
    To reduce the rejection rate, a novel control system for a continuous feedback
    control of a straightening process is presented in this paper. This leads to a
    reduction of the rejection rate and unnecessary preforming operations in wire
    straightening process. The result is an increasing sustainability and efficiency
    of these production process.

  text: The incremental flow forming process is currently enhanced in research context
    by special closed-loop property control concepts to increase the productivity
    and to control the product properties making invisible property structures like
    a magnetic barcode possible. However, it is preferred to establish property control
    concepts on single roller machines instead of conventional machines with three
    roller actuation due to the better machine accessibility. For those single roller
    machines, rather poor surface qualities of flow formed workpieces were observed
    in the past especially for hydraulic actuators. Thus, a new actuator closed-loop
    position control concept is developed in this paper using model-based control
    design methods and taking the flow forming forces as a load into account. The
    novel closed-loop control is validated during workpiece production at the actual
    single roller flow forming machine. An analysis of the manufactured workpieces
    show that the surface quality is significantly enhanced by the new control to
    a roughness level almost similar to conventional three roller flow forming. Thus,
    a sincere added value to the flow forming process is offered by the novel actuator
    closed-loop position control.

  text: In multi-stage bending and straightening operations cross-stage and quantity-dependent
    effects crucially affect the quality of the end product. Using punch-bending units
    in combination with a mechatronic straightening device can improve the accuracy
    and repeatability of product features remarkably well. In this work a concept
    for an innovative hybrid model of a roll straightener in a multi-stage straightening
    and multi-stage bending process is proposed. This model combines data-driven elements
    with expert knowledge and aims to minimise residual errors of the roll straightener
    to reliably decrease the risk of disadvantageous cross-stage and quantity-dependent
    effects on a subsequent punch-bending process.

  text: In manufacturing, property control ensures efficient part production. However,
    in reverse flow forming, current practices focus on geometry control rather than
    property control. To address the complexity of the process and tool machine interaction,
    process control is crucial for defined component properties. This study focuses
    on controlling local α’ martensite content in reverse flow forming of seamless
    AISI 304L steel tubes. Strategies and systems are presented to influence α’ martensite
    content, creating unique microstructure profiles for 1D  and 2D Gradings, with
    tangible component outcomes.

  text: <jats:title>Abstract</jats:title><jats:p>Control engineering applications
    usually require a model that accurately represents the dynamics of the system.
    In addition to classical physical modeling, powerful data‐driven approaches are
    gaining popularity. However, the resulting models may not be ideal for control
    design due to their black‐box structure, which inherently limits interpretability.
    Formulating the system dynamics in port‐Hamiltonian form is highly beneficial,
    as its valuable property of passivity enables the straightforward design of globally
    stable controllers while ensuring physical interpretability. In a recently published
    article, we presented a method for data‐driven inference of port‐Hamiltonian models
    for complex mechatronic systems, requiring only fundamental physical prior knowledge.
    The resulting models accurately represent the nonlinear dynamics of the considered
    systems and are physically interpretable. In this contribution, we advance our
    previous work by including two key elements. Firstly, we demonstrate the application
    of the above described data‐driven PCHD models for controller design. Preserving
    the port‐Hamiltonian form in the closed loop not only guarantees global stability
    and robustness but also ensures desired speed and damping characteristics. Since
    control systems based on output measurements, which are continuously measured
    during operation due to the feedback structure, we secondly aim to use this data.
    Thus, we augment the existing modeling strategy with an intelligent adaptation
    approach to address uncertainties and (un)predictable system changes in mechatronic
    systems throughout their lifecycle, such as the installation of new components,
    wear, or temperature fluctuations during operation. Our proposed algorithm for
    recursively calculated data‐driven port‐Hamiltonian models utilizes a least‐squares
    approach with extensions such as automatically adjusting the forgetting factor
    and controlling the covariance matrix trace. We demonstrate the results through
    model‐based application on an academic example and experimental validation on
    a test bench.</jats:p>

  text: <jats:title>ABSTRACT</jats:title><jats:p>This paper deals with micromagnetic
    measurements for online detection of strain‐induced α′‐martensite during plastic
    deformation of metastable austenitic steel AISI 304L. The operating principles
    of the sensors are magnetic Barkhausen noise (MBN) and eddy currents (EC), which
    are suitable for detection of microstructure evolution due to formation of ferromagnetic
    phases. The focus of this study was put on the qualification of different micromagnetic
    techniques and different measurement systems under conditions similar to the real
    ones during production, which is crucial for implementation of a property‐controlled
    flow forming process. The investigation was carried out on tubular specimens produced
    by flow forming, which have different content of α′‐martensite. To characterize
    the sensitivity of the sensors, different contact conditions between sensors and
    workpieces were reproduced. MBN sensors are suitable for detecting amount of α′‐martensite,
    but the measurements are affected by the surface roughness. This entails that
    the calibration models for MBN sensors must take account of these effects. EC
    sensors show a closer match with the amount of α′‐martensite without having major
    affectation by other effects.</jats:p>

    of the sensors are magnetic Barkhausen noise (MBN) and eddy currents (EC), which
    are suitable for detection of microstructure evolution due to formation of ferromagnetic
    phases. The focus of this study was put on the qualification of different micromagnetic
    techniques and different measurement systems under conditions similar to the real
    ones during production, which is crucial for implementation of a property‐controlled
    flow forming process. The investigation was carried out on tubular specimens produced
    by flow forming, which have different content of α′‐martensite. To characterize
    the sensitivity of the sensors, different contact conditions between sensors and
    workpieces were reproduced. MBN sensors are suitable for detecting amount of α′‐martensite,
    but the measurements are affected by the surface roughness. This entails that
    the calibration models for MBN sensors must take account of these effects. EC
    sensors show a closer match with the amount of α′‐martensite without having major
    affectation by other effects.</jats:p>

  text: In a punch-bending machine, wire products are manufactured for a wide range
    of industrial sectors, such as the electronics industry. The raw material for
    this process is flat wire made of high-strength steel. During the manufacturing
    process of the flat wire, residual stresses and plastic deformations are induced
    into the wire. These residual stresses and deformations fluctuate over the length
    of the semi-finished product and have a negative effect on the final product quality.
    Straightening machines are used to reduce this influence to a minimum. So far,
    the adjustment of a straightening machine has been performed manually, which is
    a lengthy and complex task even for an experienced worker. This inevitably leads
    to the use of inefficient straightening strategies and causes high rejection rates
    in the entire production process. Due to a lack of sensor information from the
    straightening operation, application of modern feedback control methods has not
    been practicable. This paper presents a novel design for a straightening machine
    with an integrated, precise straightening force measurement. By simultaneously
    monitoring the position of the straightening rollers, state variables of the straightening
    operation can be derived. Additionally, a tension control for feeding the flat
    wire is introduced. This is implemented to mitigate the disturbing effects caused
    by irregularities in the wire-feeding process. In the results of this article,
    the high precision of the developed force measurement design and its possible
    applications are shown.
