Co-simulation of an electric traction drive

For the simulation of electrical drives, reduced-order models or simple look-up tables are often used in order to decrease the computation time. In the latter case, the quality of the results is reduced due to interpolation. This publication introduces a coupled simulation structure which includes the control, the power electronics and also a permanent magnet synchronous machine. Each of these components is simulated in different software environments. The coupling between the different software tools is realized by a defined data flow structure. Such a structure can be useful for accurate design and system optimization. Comparison between the simulation results and experimental measurements shows that a good agreement is obtained.
