Over the past decades, the discipline of Model Order Reduction (MOR) has seen tremendous advancements in the underlying theory, leading to a wider range of applicability of the idea of "efficient computation". Similarly, applications of model order reduction to real mechatronic problems arising in industry and academia have further fed the deveolpment of theory to make the technique more practicable. At the MOR 4 MECHATRONICS 2018, internationally renowned experts will report on their recent developments, findings and insight.

The workshop will bring together theorists and practitioners working in the area of Model Order Reduction for the system level simulation of mechatronic systems.

Title: "Recent Advances in Parametric Model Order Reduction of Descriptor Systems"

Abstract: We discuss the generation of compact models of parametric dynamical systems for which a precise mathematical model or the parameter-dependence need not be known explicitly. What we assume is the availability of reduced linear models at several instances of the parameter. These could be obtained from different sources, e.g, projection-based model reduction methods, or from data-driven methods like, e.g., the Loewner framework. The reduced-models can be concatenated using certain interpolation concepts in frequency-domain using transfer function concepts as in [Baur/Benner 2009] or in time-domain as in [Panzer et al. 2010]. None of these approaches is completely satisfactory due to several aspects ("ghost poles",incompatibility of state spaces, costly evaluation of reduced-order models, ...). In this talk, we propose a new concept in order to overcome those difficulties. We illustrate this new idea by some promising computational results.


Boris Lohmann

Title: "Some Results on Parametric Reduction of linear Port-Hamilton-Systems"

Abstract: The Port-Hamiltonian representation can be advantageous for analysis, design and control of dynamical systems and is a research topic within the DFG-ANR-project “Interconnected Infinite-Dimensional Systems for Heterogeneous Media” (INFIDHEM). The talk focuses on model order reduction of such Port-Hamiltonian systems in case they depend on some parameters like geometry or material. Some results using Matrix Interpolation of linear, locally reduced models are given and an application to a discretized model of the two-dimensional wave-equations is presented, followed by a short outlook on reduction of nonlinear Port-Hamiltonian systems.

Title:"Model Reduction Inside ANSYS - from an Idea to Industrial Standard"

Abstract: Model Reduction inside ANSYS is the first and only commercial code that implements the Krylov-based model reduction. I will share experience of the code development and review the major  applications for model reduction by the industry. Finally I will present interesting open problems from the viewpoint of industrial applications.

Andreas Zilian

Title: "Modelling and analysis of flow-driven energy harvesting devices and associated
reduced-order models"

Abstract: A specific class of energy harvester devices for renewable energy resources allows conversion of ambient fluid flow energy to electrical energy via flow-induced vibrations of a piezo-ceramic composite structure positioned in the flow field. This energy converter technology simultaneously involves the interaction of a composite structure and a surrounding fluid, the electric charge accumulated in the piezo-ceramic material and a controlling electrical circuit.

The presentation will discuss a monolithic modelling approach that allows simultaneous analysis of the harvester, which involves surface-coupled fluid-structure interaction, volume-coupled electro-mechanics and a controlling energy harvesting circuit. Based on a finite element discretisation of the weighted residual form of the governing equations, time-and frequency-domain analysis enables investigation of parametrised harvester setups (geometry, flow conditions, material) and attached electrical circuits with respect to the electrical power output generated.Options for reduced-order modelling of such parametrised flow-driven energy harvesters will be discussed.


Gabriela Ciuprina

Title: "Physics Based Reduced Models for RF-MEMS Switches"

Abstract:  In this talk we propose and discuss the pros and cons of a parametric model reduction procedure tailored for MEMS switches, by runing based on physical considerations. The procedure has two main parts: one refers to the coupled multiphysics phenomena (electrical, structural, fluid flow) that appears when the switch changes its position from one stable state to the other, and the other one refers to the full wave electromagnetic phenomena, specific when the switch is in a stable state in which it is used to allow or block the propagation of RF signals.


Frank Naets

Title: "Model Order Reduction for Nonlinear Dynamics Engineering Applications"

Abstract: This presentation gives an overview of nonlinear dynamics engineering applications in modern mechatronics products design, and shows the role of (novel) MOR techniques in the design engineering process. Examples for MOR exploitation include gear design simulation, system level design optimization, full-vehicle simulation with mechatronic subsystems, durability engineering and virtual sensing for mechanical applications. It is shown how different MOR techniques play a role in obtaining a comprehensive framework for targeting different applications starting from common detailed design models. 


Athanasios C. Antoulas

Title: "Model reduction in the Loewner framework"

Abstract: One of the main approaches to model reduction of both linear and nonlinear dynamical systems is by means of interpolation. Data-driven model reduction constitutes a special case. The Loewner matrix, originally developed for rational interpolation, has been extended to the Loewner framework and constitutes a versatile approach to data-driven model reduction. Its main attribute is that it provides a trade-off between accuracy of fit and complexity of the model. The purpose of this talk will be to present the fundamentals of the Loewner framework with application to the reduction of linear switched systems.
