| 摘 要： | 介绍了电液位置伺服控制系统的组成与工作原理,并建立了系统的数学模型。将模糊控制与PID控制结合在一起,设计了模糊PID控制器,即通过模糊控制器输出对PID参数进行在线调整。利用MATLAB软件进行仿真,比较常规PID控制与模糊PID控制仿真结果,发现模糊PID控制器提高了系统的动态性能和稳态特性。

| Abstract: | In view of introduction of the composition and principle of the electro-hydraulic position servo control system,the mathematic model of the system was built.A fuzzy-PID controller was also designed by combining fuzzy logic control and PID control,for which the parameters of the PID controller can be adjusted on-line by the output of the fuzzy controller.Comparing PID controller with fuzzy-PID controller,the simulation results proved that the fuzzy-PID controller can improve the property dynamic and stabilization of the system by MATLAB software. |
