基于模糊PID位置控制器的研究

A Research of the Position Controller Based on Fuzzy-PID

介绍了电液位置伺服控制系统的组成和工作原理.传统PID控制器在受到外界干扰时,容易导致过大的超调甚至引起震荡,从而使得系统的动静态性能变差.针对此问题,设计了结合PID控制和模糊控制优点的模糊PID控制器.在MATLAB/Si mulink环境下进行仿真,结果表明,与传统的PID控制器相比,该方法改善了系统的动静态性能,同时也提高了控制系统的鲁棒性和抗干扰性.

This paper introduces the composition and principle of the electro - hydraulic position servo control system. The traditional PID controller will show bad dynamic and static state capability when a disturbance happens. The design of the Fuzzy - PID controller combining the advantages of PID control and fuzzy control with simulation by the Simulink software shows that the Fuzzy - PID controller has a better dynamic and static state performance than traditional PID controller.
