Automated symbolic model reduction for mechatronical systems

A new modelling approach for mechatronical systems using symbolic methods based on the EDA tool Analog Insydes is presented. The netlist-based modelling language has been extended for the handling of multi-domain and vector-type through and across variables. Additionally, a library of symbolic models for a basic set of mechanical components has been implemented. With this approach, an automated setup of symbolic model equations in terms of a differential-algebraic system of equations starting from a netlist description is possible. This allows the application of DAE solvers for numerical simulation as well as the application of symbolic model reduction methods of mechatronical systems.
