自抗扰控制和高频信号注入的内嵌式永磁同步电机无位置传感器控制
Sensorless control for interior permanent magnet synchronous motor based on active disturbance rejection control and high frequency signal injection technique
摘要
Abstract
Using the rotor position angle as a subject variable in extended state observer (ESO) and based on high frequency signal injection technique, a novel sensorless active disturbance rejection control system was proposed for interior permanent magnet synchronous motor. The traditional system uses current as a subject variable in its extended state observer and its rotor position value is estimated by integrating the estimated angular velocity value. So the traditional system has the problem that the error of the estimated rotor position value accumulates and increases continuously and is difficult to be eliminated. The proposed method can avoid above problem. The precision of estimated rotor position value is also high when the sine quality of current is poor because of the motor starting or load mutation. The simulation results validate the feasibility and superiority of the proposed scheme.关键词
