Simulation of hybrid mechatronic systems: a case study

Hybrid mechatronic systems consisting of continuous and discrete system parts place special requirements on the specification and simulation techniques. The electric windows of a car are used as a case study to evaluate the authors' ideas in this area. For the specification of the continuous part (e.g. the motor) a description in DSL or a block diagram is used, whereas the discrete part is specified by an automaton. The interconnections are modelled by extended predicate/transition nets. For a first simulation the different descriptions are transformed into predicate/transition nets to get a uniform formalism. For more complex systems or a hardware-in-the-loop simulation the parallelisation of the hybrid simulation is necessary.
