Integral Sliding Mode Variable Structure Control of Synchronous Reluctance Motors

Abstract

Aiming at the problem of jitter in the speed when the load changes abruptly during the operation of a synchronous reluctance motor and the poor resistance to load disturbance, an integral type sliding film variable structure control algorithm is proposed. The speed regulation is controlled by sliding mode, PI controls the current regulation, the Simulink simulation model of the system is built, and simulation experiments are conducted. The results show that, compared with the traditional PI control, the system’s dynamic response is faster, the resistance to load disturbance is stronger, and the robustness is high.
