机载全数字跟踪平台的设计

Design of Airborne All Digital Tracking Platform

根据机载电视跟踪系统的具体情况,提出了基于PC/104嵌入式计算机构成的具有速度环和位置环的数字伺服跟踪系统,它由陀螺的负反馈完成对速度环的稳速,由编码器完成位置环的控制,并采用了一种非标准的PID控制器实现对目标的跟踪控制。实际应用表明,该控制器具有对低阶、高阶、延迟时间等能够产生自适应响应。

A digital servo tracking system with velocity loop and location loop constituted by PC/104 embedded computer based on the concrete condition of airborne TV tracking system is presented.The negative feedback of gyroscope stabilizes its velocity loop and the coder controls its location loop.It adopts a non-standard PID controller to realize the tracking control of objects.The real application demonstrates that the controller can generate adaptive responses for low order,high order and delay-time.
