摘　　要：简要介绍了卡尔曼滤波理论及其算法,并通过一个实例证明了卡尔曼滤波器所具有的出色的滤波性能;利用MATLAB对伺服系统中直流电动机进行了建模,在此基础之上,用卡尔曼滤波技术进行了仿真研究,并与传统的PID控制进行了比较,比较结果证明了该方法的有效性。The theory of the Kalman filter and its algorithm were introduced, and its excellent filtering performance was proved by an example. The DC motors model of servo system using MATLAB was built,on the basis of the model,the Kalman filter technic was emulated. And the result of the emulation with the conventional PID controller was compared. The comparison result proved the availability of the method.
