卡尔曼滤波器在直流无刷电动机控制系统中的应用

The Application of Kalman Wave Filter to the Controlling System of Brushless DC Motor

针对直流无刷电动机在使用普通的位置传感器(如霍尔元件等)时所产生的误差问题,采用软件算法来得到电动机的轴位置传号。因此,从物理上消除了电动机所需要的轴位置传感器和其它与该传感器有关的元件。用卡尔曼滤波的方法可以在改善系统控制性能的情况下进一步节约同极系统的成本。

Due to the mistakes produced by the brushless dc motor when using general position sensor （Hall Element, etc. ）, software arithmetic was adopted to obtain motor＇s axis position mark. The axis position sensor and other relevant elements are not physically necessary. Kalman wave filtering can better system controlling performance as well as save the cost of homopolarity system.
