模糊PID控制在船载测控系统中的应用研究

Study on Fuzzy-PID Control Servo System for Ship-borne TT&C Systems

针对目前船载测控雷达天线伺服系统中采用传统PID控制存在超调量大、响应时间长等不足,比较了传统PID控制和模糊控制的不同特点,讨论了模糊PID控制器的设计方法,并利用MATLAB软件对系统进行了辅助设计与仿真实验。仿真结果表明,该控制方法可以提高伺服系统的快速性和平稳性,有效增强船载测控系统的跟踪性能。

This thesis is aimed at overcoming the drawbacks,e.g.overshoot and long response time when using traditional PID in ship-borne TTC servo systems.The features of traditional PID control and fuzzy control are compared and a design method of fuzzy-PID controller is presented.Then,an example is given to show how to design and simulate the system using MATLAB.Simulation results show that the performance of ship-borne TTC servo systems is improved using the proposed controller.
