| 摘 要： | 提出了一种基于卡尔曼滤波器理论的永磁同步电机定子磁链观测的新方法,着重分析了卡尔曼滤波器的设计原理,最后将该方法运用到永磁同步电机直接转矩控制系统中。仿真结果证明该方法具有良好的观测效果,完全消除了常规电压积分磁链观测方法存在的直流偏移和累积误差等缺点。

| Abstract: | A new means of observation of stator flux linkage of permanent magnet synchronous motor based on kalman filter is proposed, then the design theory of kalman filter is emphasized. Finally the means is applied to a control system of direct torque control for permanent magnet synchronous motor and the result of simulation show that the new means has better observation result of flux linkage. It can entirely eliminate direct current departure and accumulating error. |
