摘要
介绍了一种基于扩展卡尔曼滤波的永磁同步电机无传感器转子位置与速度估算方法,并以此为基础实现了永磁同步电机的无传感器矢量控制系统。通过测量流过电机定子电流和电机端电压在线估计电机转子的位置和速度,实现永磁同步电机的无传感器控制策略。仿真和实验结果验证了该方案的可行性及有效性。
A method of estimating the rotor position and speed based on extended Kalman filter（EKF） for permanent magnet synchronous motor（PMSM） is proposed.A scheme of sensorless drive of PMSM can be realized by using this method.By using monitoring stator voltages and currents,it is possible to estimate the rotor position and speed and implement PMSM drives without position and speed sensors.Simulation and experimental results show the feasibility and effectiveness of this algorithm.
