摘　　要：为了提高雷达位置伺服系统的跟踪能力,缩短系统的响应时间,在原模拟伺服系统中加入计算机作为控制器。系统采用自校正PID控制方法对雷达天线进行位置跟踪,避免了一般的数字PID控制时参数无法在线调整的缺点,并通过Matlab进行了仿真。仿真结果表明,所设计的控制器应用在雷达伺服系统中能达到满意的控制效果,响应速度较快。In order to enhance the tracking capability of radar servo system and cut down the response time of the system, a computer is added in existing analog servo system as the controller. By using self-tuning PID control method , the position tracking of radar antenna is implemented. It avoided the demerit that it is impossible to adjust parameters online with common digital PID control. The system is simulated with Matlab, the results indicate that the controller meets satisfactory control effects in radar servo system and the response speed is faster.
