摘　　要：雷达伺服系统是雷达的重要组成部分,传统PID控制方法难以满足现代雷达对伺服控制系统更高精度、更高稳定性等的需求。文中针对雷达伺服系统的位置环,提出了一种改进鸡群优化算法(Improved Chicken Swarm Optimization,ICSO)与模糊PID控制相结合的复合控制策略(ICSO-FUZZY-PID)。利用Matlab/Simulink的辅助设计和强大仿真功能,对比了雷达伺服系统分别在传统PID控制和ICSO-FUZZY-PID控制下的运行状况。仿真结果表明,应用ICSO-FUZZY-PID控制的雷达伺服系统响应速度更快,控制精度更高,自适应能力更强,具有较好的动静态特性。The radar servo system is an important part of the radar.The traditional PID control method can not meet the requirement for higher precision and stability of the servo control system.Aiming at the position loop of radar servo system,an improved chicken swarm optimization(ICSO)combined with fuzzy PID control strategy(ICSO-FUZZY-PID)is proposed in this paper.By using the auxiliary design and powerful simulation function of Matlab/Simulink,the operation status of radar servo system under traditional PID control and ICSO-FUZZY-PID control are compared.The simulation results show that the radar servo system controlled by ICSO-FUZZY-PID has faster response speed,higher control precision and stronger adaptive ability and has better dynamic and static characteristics.
