摘　　要：针对永磁同步电机(PMSM)高频注入无感算法在估算电机角度时容易产生滞后而影响转速控制精度的问题,提出了一种基于线性自抗扰控制的永磁同步电机无传感器控制策略。通过使用简化的线性自抗扰控制算法,对永磁同步电机速度闭环进行优化控制,同时采用高频正弦电压注入的无传感器角度观测算法,获取电机转子的角度及转速信息。最后,通过仿真分析与实物试验,验证了该控制策略可以有效提高永磁同步电机转子角度与转速的估算精度,提升系统的控制效果,且具有较好的工程应用前景。The high frequency injection sensorless control algorithm of permanent magnet synchronous motor(PMSM)is prone to lag when estimating motor angle,which affects the accuracy of speed control.To solve this problem,a sensorless control strategy of PMSM based on linear active disturbance rejection control is proposed.The speed closed-loop of PMSM is optimized by using simplified linear active disturbance rejection control algorithm.Simultaneously,a sensorless angle observation algorithm using high-frequency sinusoidal voltage injection is used to obtain the angle and velocity information of the motor rotor.Finally,through simulation analysis and physical experiments,it was verified that the control strategy can effectively improve the estimation accuracy of motor angle and speed of PMSM,improve the control effect of the system,and have good prospect of engineering application.
