Course contents:The time dependent behaviour of mechatronic systems, often including coupled physical effects (e.g., mechanical and electrical coupling), is of great importance for their design and application. Through the spatial discretization of the governing partial differential equations, for example using the finite element method, we obtain very large ordinary differential equation systems, which often cannot be solved efficiently.
In this lecture students will be introduced to Model Order Reduction Methods, which allow to automatically obtain smaller/compact models, enabling so, efficient but accurate simulation of the same multi-physical phenomena. The methods will be demonstrated on a number of relevant microsystem applications. The industry tools for system-level simulation of multiphysical systems, like ANSYS, mor 4 ANSYS, Slicot Simplorer, Saber will be used.
