摘 要: 使用带渐消因子的自适应卡尔曼滤波(adaptive Kalman filter)构造了永磁同步电机(permanent magnet synchronous motor,PMSM)的速度观测器。该滤波器根据PMSM的输出,在线自适应调整渐消因子,从而使滤波器在电机模型存在误差或电机受到外扰的情况下仍收敛并保持最佳,同时具有高收敛速率的特点。另外,对基于渐消卡尔曼滤波器的PMSM进行Mtalab仿真实验。仿真结果表明:该观测器能有效实现电机的转速观测,具有良好的动、静态特性。

Abstract: The adaptive Kalman filter with fading factor is used to construct the permanent magnet synchronous motor (PMSM) speed observer in this paper. According to the output of the PMSM, the filter can on�line adaptively adjust the fading factor, so that the filter still maintains the best convergence, and with a high convergence rate, on the condition that the model error or the interference by outside circumstances is existed. Finally, the test of the PMSM based on fading Kalman filter for Matlab simulation is established. The simulation results confirm that the proposed observer can estimate the motor speed effectively and can achieve a perfect dynamic and statistic performance.
