英文摘要：

The speed fluctuation of Two-Stage Matrix Converter （TSMC） drive Permanent Magnet Synchronous Motor （PMSM） vector control system is very big in load disturbance cases, a new rate reaching law sliding mode control algorithm was applied to control system speed, in Matlab/Simulink software system simulation platform was built, when compared with conventional PI control algorithm, it was verified that the proposed new reaching law sliding mode control algorithm could enhance ability of the two-stage matrix converter drive permanent magnet synchronous motor vector control system to resist load disturbance, and improve the dynamic performance of the speed, and still effectively restrain chattering in the conventional sliding mode control structure.
