论文综合永磁同步电机控制系统和无位置传感器控制技术的分类和发展趋势,主要研究了基于扩展集员滤波的永磁同步电机的无位置传感器的控制系统。结合扩展集员滤波算法(ESMF)建立了基于ESMF的无传感器PMSM矢量控制系统,实时估算电机的转速和位置。对比了测量转速与估计转速,以及测量位置与估计位置,仿真实验结果表明,基于ESMF的无传感器PMSM矢量控制系统具有快速的转速响应特性和良好的稳定性。

This paper integrates the classification and development trend of permanent magnet synchronous motor control system and positionless sensor control technology,and mainly studies the control system of the permanent magnetic synchronous motor based on the expansion collector filter.The Sensor-less PMSM vector control system based on ESMF is established in combination with the expansion set filtering algorithm(ESMF)to estimate the speed and position of the motor in real time.Comparing the measured rotational speed with the estimated rotational speed,as well as the measuring position and the estimated position,the simulation results show that the sensor less PMSM vector control system based on ESMF has fast speed response characteristics and good stability.
