摘要
针对红外制导空空导弹导引头瞬时视场角小、对目标发现概率低的问题,提出了导引头预定回路模糊PID双模控制方案。首先对导引头伺服系统工作原理进行分析,建立其预定回路模型;其次,对预定回路分别采用常规PID控制和模糊PID控制进行了仿真对比分析;最后给出了预定回路的模糊PID双模控制模型,并进行了仿真验证,结果表明该方案能有效改善导引头动态性能,提高发现概率。
In order to overcome the problems of small instantaneous FOV angle of missile seeker and low probability of target detection, a method of dual fuzzy PID control of scan loop was presented. Firstly, the scan loop model was set up based on the analysis of servo system. Secondly, the results of normal PID control and fuzzy PID control on scan loop were compared; At last, the dual fuzzy PID control of scan loop was put forward. By simulation and validation, the seeker＇s dynamic performance can be improved and the detecting probability of target can be enhanced effectively with the method.
