摘要

本文利用扩展卡尔曼滤波算法(EKF)，仅通过测量相电压和电机电流来控制永磁同步电动机无传感器直接转矩控制(DTC)的速度问题。此外，由于采用了带有误差跟踪的角度修正方案，无传感器驱动系统对参数变化具有鲁棒性。仿真结果验证了该方法的有效性。

Sensor-less direct torque control of permanent magnet synchronous motor drive using Extended Kalman filter

This paper presents the control of the speed problem for a Sensor-less Direct Torque Control (DTC) of permanent magnet synchronous motor (PMSM), using the Extended Kalman Filter algorithm (EKF) by only measuring the phase voltages and motor currents. Also, due to an angle modification scheme with error tracking, the Sensor-less drive system is robust to parameter variations. Simulation result is provided to verify the proposed approach based on the EKF.
