| 摘 要： | 针对一类含输出齿隙非线性的伺服控制系统，提出了2种克服齿隙影响系统跟踪精度的方法。对大型雷达天线伺服系统，采用了电消齿隙、差速负反馈的多电机联动新方法，并已应用于某天线伺服系统，获得了很高的跟踪精度。针对单电机驱动的含齿隙伺服系统，提出了一种智能比例、积分和微分（PID）控制器及基于规则的补偿控制策略。实际系统调试结果表明，该方法有效地提高了系统的定位和跟踪精度。

| Abstract: | Two methods of antibacklash are proposed for a class of servo systems with backlash affecting tracking precision. Multi motor method, which includes antibacklash and negative feedback based on the difference of velocity of two motors , is designed for large radar antenna servo systems. It was successfully used for some antenna system, and the performance of the system was improved greatly. For single motor servo system, intelligent PID and rule based compensation strategy are presented. Practical application shows that it can improve position precision and tracking precision with effect. |
