Realtime simulation of control algorithms including the dedicated control hardware

A number of different steps are necessary to develop power-electronic systems: After preparation of a concept, the layout of the controller is made based on simulation. The process is finalised by implementation and test on the power-electronic system itself. A successful final test requires, however, that the controller hardware controlling the power-electronic system functions properly. Additionally, the control software must be implemented correctly and function properly. At this point, a real-time simulator becomes useful which allows to verify the function of the controller hard- and software in real-time. This is realized by simulating the entire controlled system - including the power electronics - by means of state equations in a simulation algorithm. This method offers the possibility to test the control hardware without endangering the costly power electronics.
