模糊自适应PID控制器在液压伺服系统的应用

Fuzzy Self-adaptation PID Controller's Application in the Hydraulic Servo System

将模糊控制器和PID控制器结合在一起,利用模糊控制实现了PID控制器参数在线自调整,进一步完善了PID控制器的性能,提高了液压伺服系统的控制精度。实验与仿真结果表明:模糊自适应PID控制器,具有良好的动态、稳态性能以及较强的鲁棒性。

The using of fuzzy control makes the parameter＇s self-adaptation of PID controller realized when the fuzzy controller is combined with the PID controller together. It notonly perfects the performance of the PID controller but also improves the pre- cision of the hydraulic servo system. The simulation and comparison show that the fuzzy self-adaptatlon PID controller has the dynamic and steady performance and the robustness.
