| 摘 要： | 研究了利用扩展卡尔曼滤波器(extended kalman filter, EKF)对永磁同步电机(permanent magnet synchronous motor, PMSM)矢量控制系统进行参数精确估计的方法。通过引入定子电流和电压，在线估计电机的定子磁链、电机转速和转子位置，进而实现永磁同步电机的无传感器控制。仿真结果表明EKF准确地观测了电机转速和磁链，所构建的无速度传感器矢量控制系统具有良好的控制性能。

| Abstract: | A speed estimation method of permanent magnet synchronous motor(PMSM) for sensorless vector control based on Extended Kalman Filter(EKF) is proposed in this paper. By introducing the stator voltage and current, estimating the stator flux ,speed and position of the rotor on line ,and thus realize the sensorless vector control of PMSM. The simulation results show that this method can estimate the speed and flux accurately and improve the performance of the sensorless vector control of PMSM. |
