摘要：

The traditional proportion integral derivative (PID) control is widely used in permanent magnet synchronous motor (PMSM) control systems for its simplicity, but it is difficult to meet the need of high performance. Though the traditional sliding mode control (SMC) has a good performance in a certain extent, it needs the speed differential signals which will cause high frequency disturbances. In order to realize high precision control, this paper designed a kind of integral type sliding mode variable structure controller and a load torque observer. The observer can observe the change of the load torque rapidly. And the sliding mode controller can keep the speed constant. System simulation and experimental results show that the system has the advantages of rapidity, no over-shoot and resistance to load disturbance. © 2014 Chin. Soc. for Elec. Eng.
