新型Luenberger观测器的高速永磁同步电机无传感器控制
Sensorless Control of High Speed Permanent Magnet Synchronous Motors with Novel Luenberger Observer
摘要
Abstract
In this paper,a new Luenberger observer and sensorless rotor position detection strategy of high-speed permanent magnet synchronous motor based on fuzzy PI phase-locked loop are proposed.The new Luenberger observer uses the pole configura-tion idea to change the feedback gain according to the motor speed to avoid the excessive motor speed affecting the rotor position esti-mation accuracy.Aiming at the large error of the rotor position of the forward and reverse switching rotor of the motor once the PI con-troller parameters in the traditional phase-locked loop are set,a fuzzy PI control algorithm is proposed to self-tune the PI parame-ters of the phase-locked loop.The sensorless rotor position detection method proposed in this paper can accurately detect the rotor position information at high speed.Finally,the proposed rotor position detection method is compared with the traditional rotor posi-tion detection method,and the feasibility of the proposed method is proved by experiments.关键词
