摘要
使用带渐消因子的自适应卡尔曼滤波构造了永磁同步电机的速度观测器。该滤波器根据永磁同步电机的输出,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。最后对基于渐消卡尔曼滤波器的永磁同步电机进行仿真实验。仿真结果表明,该观测器能有效地实现电机的转速观测,具有良好的动、静态特性。
The adaptive Kalman filter with fading factor was used to construct the permanent magnet synchronous motor（PMSM） speed observer.According to the output of the PMSM,the filter can adaptively adjust the fading factor on-line,so that the filter still maintains the best convergence and possesses a high convergence rate even when the model error or the interference by outside circumstances is existed.Finally,the test of the PMSM based on fading Kalman filter was established in Matlab.Simulation results confirm that the proposed observer can estimate the motor speed effectively and can achieve a perfect dynamic and static performance.
