依托于光电稳瞄平台的理论模型来进行实测频率特性的系统辨识,由此建立与理论和实测模型均较吻合的系统仿真模型.并针对光电稳瞄平台的系统要求和应用特性设计了模糊+经典复合型控制方法.经典方式的零极点配置控制器低频增益高、系统稳态误差小.实际应用表明:光电稳瞄平台的隔离度达到了1%以内,实测的系统稳像精度达到较高的指标要求.二维模糊控制器可减小系统超调、缩短系统响应时间、并适当提高系统响应带宽,采用智能协调器切换经典控制器和模糊控制器,使系统的隔离度小于1%的同时,将超调从50%减少到4%,达到较好的控制效果.
Based on the theoretical model of the electrooptical aim platform system,the actual frequency characteristic of the system was identified,and the simulink model of the system,which anastomose with the theoretical model and the actual frequency characteristic,was obtained.According to the demand and application characteristics of the electrooptical aim platform system,the fuzzy + classical complex controller was designed.Classical zeropole assignment controller has the characteristic of high lowfrequency gain and small steady error.Actual application implies that the isolation of the electrooptical aim platform system has reached 1%.The actual precision has arrived at the target demand.Planar fuzzy controller can decrease the overshot,shorten the rise time,and increase the bandwidth.Using intelligent coordinator to switch classical controller and fuzzy controller,the isolation is <1%, and the overshot decreases from 50% to 4%.
