一种新型永磁同步电机高频脉冲注入无感控制方法
A Novel Non-inductive Control Method for High-frequency Pulse Injection of Permanent Magnet Synchronous Motor
摘要
Abstract
The back electromotive force(EMF)increases with the speed of the motor,that is,the faster the speed,the greater the back EMF,and when running at low speed,the traditional permanent magnet synchronous motor(PMSM)has no position sensor control technology,and the signal-to-noise ratio of the useful signal is very low,resulting in the reduction of the detection accuracy of the motor rotor position and speed.In order to obtain the position information of the rotor without the position sensor in the operation of the permanent magnet synchronous motor,a method based on high-frequency pulse voltage injection was adopted,and an improved second-order generalized integrator was used for frequency selection.By introducing a high-frequency voltage into the q-axis,the rotor error information was extracted,and the detected high-frequency current response in the q-axis was used to track the rotor position in real time.Theoretical,simulation and experimental results show that the proposed method can improve the estimation accuracy of real-time rotor position information in the low speed range,and shows good robustness.关键词
