  text: In control design most control strategies are model-based and require accurate
    models to be applied successfully. Due to simplifications and the model-reality-gap
    physics-derived models frequently exhibit deviations from real-world-systems.
    Likewise, purely data-driven methods often do not generalise well enough and may
    violate physical laws. Recently Physics-Guided Neural Networks (PGNN) and physics-inspired
    loss functions separately have shown promising results to conquer these drawbacks.
    In this contribution we extend existing methods towards the identification of
    non-autonomous systems and propose a combined approach PGNN-L, which uses a PGNN
    and a physics-inspired loss term (-L) to successfully identify the system's dynamics,
    while maintaining the consistency with physical laws. The proposed method is demonstrated
    on two real-world nonlinear systems and outperforms existing techniques regarding
    complexity and reliability.

  text: 'While trade-offs between modeling effort and model accuracy remain a major
    concern with system identification, resorting to data-driven methods often leads
    to a complete disregard for physical plausibility. To address this issue, we propose
    a physics-guided hybrid approach for modeling non-autonomous systems under control.
    Starting from a traditional physics-based model, this is extended by a recurrent
    neural network and trained using a sophisticated multi-objective strategy yielding
    physically plausible models. While purely data-driven methods fail to produce
    satisfying results, experiments conducted on real data reveal substantial accuracy
    improvements by our approach compared to a physics-based model. '

  text: "Ultrasonic wire bonding is a solid-state joining process used to form electrical
    interconnections in micro and\r\npower electronics and batteries. A high frequency
    oscillation causes a metallurgical bond deformation in\r\nthe contact area. Due
    to the numerous physical influencing factors, it is very difficult to accurately
    capture\r\nthis process in a model. Therefore, our goal is to determine a suitable
    feed-forward control strategy for the\r\nbonding process even without detailed
    model knowledge. We propose the use of batch constrained Bayesian\r\noptimization
    for the control design. Hence, Bayesian optimization is precisely adapted to the
    application of\r\nbonding: the constraint is used to check one quality feature
    of the process and the use of batches leads to\r\nmore efficient experiments.
    Our approach is suitable to determine a feed-forward control for the bonding\r\nprocess
    that provides very high quality bonds without using a physical model. We also
    show that the quality\r\nof the Bayesian optimization based control outperforms
    random search as well as manual search by a user.\r\nUsing a simple prior knowledge
    model derived from data further improves the quality of the connection.\r\nThe
    Bayesian optimization approach offers the possibility to perform a sensitivity
    analysis of the control\r\nparameters, which allows to evaluate the influence
    of each control parameter on the bond quality. In summary,\r\nBayesian optimization
    applied to the bonding process provides an excellent opportunity to develop a
    feedforward\r\ncontrol without full modeling of the underlying physical processes."

  text: Modern traffic control systems are key to cope with current and future traffic
    challenges. In this paper information obtained from a microscopic traffic estimation
    using various data sources is used to feed a new developed traffic control approach.
    The presented method can control a traffic area with multiple traffic light systems
    (TLS) reacting to individual road users and pedestrians. In contrast to widespread
    green time extension techniques, this control selects the best phase sequence
    by analyzing the current traffic state reconstructed in SUMO and its predicted
    progress. To achieve this, the key aspect of the control strategy is to use Model
    Predictive Control (MPC). In order to maintain realism for real world applications,
    among other things, the traffic phase transitions are modelled in detail and integrated
    within the prediction. For the efficiency, the approach incorporates a fuzzy logic
    preselection of all phases reducing the computational effort. The evaluation itself
    is able to be easily adjusted to focus on various objectives like low occupancies,
    reducing waiting times and emissions, few number of phase transitions etc. determining
    the best switching times for the selected phases. Exemplary traffic simulations
    demonstrate the functionality of the MPC-based control and, in addition, some
    aspects under development like the real-world communication network are also discussed.

  text: Within this work, we investigate how data-driven numerical approximation methods
    of the Koopman operator can be used in practical control engineering applications.
    We refer to the method Extended Dynamic Mode Decomposition (EDMD), which approximates
    a nonlinear dynamical system as a linear model. This makes the method ideal for
    control engineering applications, because a linear system description is often
    assumed for this purpose. Using academic  examples, we simulatively analyze the
    prediction performance of the learned EDMD models and show how relevant system
    properties like stability, controllability, and observability are reflected by
    the EDMD model, which is a critical requirement for a successful control design
    process. Subsequently, we present our experimental results on a mechatronic test
    bench and evaluate the applicability to the control engineering design process.
    As a result, the investigated methods are suitable as a low-effort alternative
    for the design steps of model building and adaptation in the classical model-based
    controller design method.

  text: The implementation of control systems in metal forming processes improves
    product quality and productivity. By controlling workpiece properties during the
    process, beneficial effects caused by forming can be exploited and integrated
    in the product design. The overall goal of this investigation is to produce tailored
    tubular parts with a defined locally graded microstructure by means of reverse
    flow forming. For this purpose, the proposed system aims to control both the desired
    geometry of the workpiece and additionally the formation of strain-induced α′-martensite
    content in the metastable austenitic stainless steel AISI 304 L. The paper introduces
    an overall control scheme, a geometry model for describing the process and changes
    in the dimensions of the workpiece, as well as a material model for the process-induced
    formation of martensite, providing equations based on empirical data. Moreover,
    measurement systems providing a closed feedback loop are presented, including
    a novel softsensor for in-situ measurements of the martensite content.

  text: One of the main objectives of production engineering is to reproducibly manufacture
    (complex) defect-free parts. To achieve this, it is necessary to employ an appropriate
    process or tool design. While this will generally prove successful, it cannot,
    however, offset stochastic defects with local variations in material properties.
    Closed-loop process control represents a promising approach for a solution in
    this context. The state of the art involves using this approach to control geometric
    parameters such as a length. So far, no research or applications have been conducted
    with closed-loop control for microstructure and product properties. In the project
    on which this paper is based, the local martensite content of parts is to be adjusted
    in a highly precise and reproducible manner. The forming process employed is a
    special, property-controlled flow-forming process. A model-based controller is
    thus to generate corresponding correction values for the tool-path geometry and
    tool-path velocity on the basis of online martensite content measurements. For
    the controller model, it is planned to use a special process or microstructure
    (correlation) model. The planned paper not only describes the experimental setup
    but also presents results of initial experimental investigations for subsequent
    use in the closed-loop control of α’-martensite content during flow-forming.
