Control simulation for switched reluctance motor system based on finite element model

The control simulator Simulink was used to model and simulate the Switched Reluctance Motor (SRM) drive system based on finite element model. This used the accuracy of finite element method and the rapidity of control simulator to analyze the nonlinear characteristics and dynamic characteristic of motor, where the geometry structure, electromagnetic parameters, outside drive circuit and control circuit were simulated and studied as a whole. The design to control and static to dynamic performance of SRM were considered by data transferring from ANSYS to Simulink. A simulation was taken for a prototype motor under Chopped Current wave Control (CCC) and Angle Position Control (APC) during low speed and high speed respectively. The results of simulation are corresponding with theoretical analysis, which validate the effective of the finite element model and control model. Seen from the result, the torque ripple coefficient is reduced to about one quarter of initial simulation by selecting an appropriate shutoff angle.
