Abstract
The disturbance of given signals and external loads has an undeniable impact on the output of permanent magnet synchronous motor.To improve the stability of permanent magnet synchronous motor under various operating conditions,adopting advanced control algorithms is of great significance in improving the control effectiveness of the system.In this paper,a new control strategy is designed by combining backstepping control and sensorless control.This method takes advantage of the characteristics of backstepping control,such as good global stability,excellent dynamic and static performance,which can effectively suppress the disturbance caused by load changes.At the same time,the system uses an extended Kalman filter to identify the relevant process parameters,providing the controller with the current operating state of the motor.The mathematical model of the permanent magnet synchronous motor control system was derived in the article,and simulation experiments were conducted using MATLAB.The simulation results show that compared with traditional backstepping control systems,the permanent magnet synchronous motor drive system with sensorless can control the motor speed effectively,and has good dynamic and static characteristics and robustness.关键词
