【Abstract】 Switched reluctance motor drive system (SRD) is a nonlinear system which include s the motor, the power converter and the control circuit. Based on the mathemati cal model of the switched reluctance motor (SRM), under Matlab/Simulink environ men t, the hysteresis current controller block, the power converter block, the rotor angle calculating block, etc. were modeled. By the combination of these blocks, the nonlinear model of SRD under chopped current control (CCC) can be establi shed easily. In term of this model, simulation of a four-phase 8/6 structure m otor was made. The effectiveness of the nonlinear simulation models is demonstr ated by the simulation results. The models also offer a valid tool for analyzing and designing SRM control system.更多还原
