摘要
Abstract
The backstepping control method was proposed due to the nonlinear characteristics of permanent magnet synchronous motor. The design of the method was simple, and it can decouple the control system completely so the method can achieve better control than traditional PI control method. Because of the temperature changes, resistance value will change also. We present a combination method of Adaptive Control and the backstepping control method to overcome the instability of the system influenced by parameters. In addition,we design a load torque sliding mode observer to reduce the influences of load change. The observed load torque was used for feed-forward compensation. Simulation results show that the adaptive backstepping control and the load observer can effectively improve the dynamic response speed of the control system,and make the system has strong robustness.关键词
