针对空间光通信中跟踪系统的高精度、宽带宽要求,提出了一种基于PID神经元网络(Proportional integral differential neural network-PIDNN)的控制方案。采用MATLAB对所建立的跟踪系统模型进行了仿真分析研究,对采用PIDNN控制器的精跟踪系统的在线训练能力及学习、调整功能进行了仿真验证,同时加入扰动源对精跟踪系统的稳态、动态性能及鲁棒性进行了仿真测试。仿真和测试结果表明:通过PIDNN控制的精跟踪系统具有良好的稳态及动态性能和很强的鲁棒性,系统跟踪精度高且系统带宽较宽。

A control scheme based on proportional integral differential neural network(PIDNN) was proposed to control the high precision and wide band tracting system in spcace communication.　Firstly,　the models of tracting system was simulated, analyzed and studied with MATLAB.　Secondly,　the PIDNN controller for its on-line training,　learning and regulating ability was used to control the system in simulation environment.　Whats more,　the scrambler was used to test the performace of static and dynamic and robust.The simulation results show that fine tracting system based on PIDNN has a well static and dynamic and robust character,has the properties of nice steady accurary and wide band.
