摘要:

以仿真转台运动模拟光电目标，基于双DSP处理器和精密的机械转台搭建了空间光通信二维实验演示系统。软件上基于TMS320F2812处理器实现了卡尔曼预测控制算法，将该算法与常规的PID经典控制相比较，并进行了卡尔曼预测控制算法验证实验研究。实验结果表明：相比于常规的PID算法，在保证足够的系统采样点数，卡尔曼预测控制具有较好的控制效果。

Abstract:

The two dimensional experimental demonstration system of free space optical communication was designed and built based on dual DSP processor and precision mechanical turntable. In this system, the motion of photoelectric target was substitute of simulation turntable. The Kalman predictive control algorithm was achieved in the processor of TMS320F2812, and it was compared with conventional PID classical control. Experiment studies were carried out to verify the Kalman forecast control algorithm and the results show that, compared to conventional PID algorithm, the Kalman predictive control achieves better control effect under the condition of adequate sample points.
