摘要
在空间光通信中,为实现准确捕获和高精度跟踪,ATP系统采用复合轴控制技术。复合轴控制系统的主轴控制,即粗跟踪控制, 其系统由速度环路和位置环路组成, 控制过程由TMS320VC5416 高性能DSP芯片来完成。仿真和实验结果表明,主轴控制系统的跟踪精度在1 以内,满足ATP系统对精度的要求。
In space optical communication, in order to realize exact acquisition and high-accuracy tracking, combined axis control technique is applied in ATP(Acquisition, Tracking, and Pointing) system. The main control of combined axis control system is coarse tracking control. The system is composed of a speed loop and a position loop and the control process is carried out by high-performance DSP chip TMS320VC5416. Simulation and experimental results show that the tracking accuracy of the main axis control system is not bigger than 1 angle minute and this fulfills the demands of ATP system.
