摘　　要：红外成像目标模拟器方位系统是一参数快时变系统 ,针对该系统的具体情况 ,提出了一种对偶自校正 PID控制器 .在每一自适应步 ,通过谱分解得到最优 PID参数 ,然后基于双重指标进行对偶校正 ,得到一种既保持对偶效应 ,又十分简单易行的对偶自校正 PID控制器 ,成功地消除了传统自适应控制系统的“关断”、“终止”和“猝发”等现象 ,收到了良好的控制效果 .该控制器适于参数随机变化或快时变系统 .Azimuth system of infrared photogenic objective simulator is a system of fast time varying parameters. A dual self tuning PID controller is presented with respect to the special case of the system. At each adaptive step, the optical parameters of PID controller are derived through online spectral factorization, then the controller is modified based on bicriteria. And a dual self tuning PID controller that has dual effectiveness is derived and it is very simple for implementation. It successfully eliminates “turn off”,“windup” and “bursting” phenomena of conventional adaptive control systems. This controller is suitable for stochastic parameters or fast time varying systems.
