Integral Sliding Mode Variable Structure Control of Synchronous Reluctance Motors

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