Base on the mathematical mo el of the switche reluctance motor ( SRM) , un er Matlab/ Simulink environment, the hysteresis current controller block, the power converter block, the rotor angle calculating block, etc. were mo ele . By the combination of these blocks, the nonlinear mo el of SRD un er choppe current control ( CCC) can be establishe easily. In term of this mo el, simulation of a four-phase 8/ 6 structure motor was ma e. The effectiveness of the nonlinear simulation mo els is emonstrate by the simulation results. The mo els also offer a vali tool for analyzing an esigning SRM control system. Key words: switche reluctance; Matlab/ Simulink; CCC; nonlinear; mo eling an simulation ( SRM) , [ 1] . , , , SRM , .
