摘要
为解决光电跟踪伺服系统中的计算资源不足的问题,分析了光电跟踪伺服系统跟踪回路的结构,设计了基于双数字信号处理器的数字伺服控制硬件平台,以完成光电跟踪系统的通信、扰动隔离以及目标跟踪等功能,介绍了其硬件与软件实现方法;对各DSP任务进行了合理规划,以McBSP接口作为双DSP的数据交换接口,保证了通讯的实时性。以方位轴跟踪回路为例,构建了脱靶量预测滤波算法,实现了等效复合控制。
In order to satisfy the resource requirement of electro optical tracking servo system, a digital servo hardware platform based on dual DSPs is developed, fulfilling functions such as communication, disturbance rejection and target tracking etc. Different tasks was dispatched for each DSP, and real-time communication was performed via McBSP. Using this platform, control algorithms were developed such as prediction filter for compound control, giving a example of azimuth axis.
