摘　　要：通过研究卡尔曼滤波器的信号模型,采用KALMAN滤波器同常规PID控制相结合的方法对系统进行仿真研究,利用卡尔曼滤波器来克服系统中的测量噪声和控制噪声对控制性能的影响。结果表明:同没有加卡尔曼滤波器的常规PID控制相比,卡尔曼滤波器很好地抑制了白噪声的污染,控制效果明显改善。Through the study of Kalman filter signal model, Kalman filter is combined with general PID control method to simulate the system by researching the signal model of kalman filter. Kalman filter is used to overcome measurement noise of system and the impact of control noise for the control performance. The result of simulation shows that the white noise was suppressed and the control effect had been improved notably because of kalman filter, compared with the general PID control without kalman filter.
