Simulating Human Intelligence Fuzzy Adaptive Control of Electro—Hydraulic Position Serve System

本文针对电液位置伺服系统本身固有的非线性等特点,设计和实现了一种仿人智能型模糊一自适应控制器。仿真和实验结果表明,该方法能显著地改善系统的动态特性,提高了稳态定位精度,有效地克服非线性等因素的影响,且对参考模型不敏感,表现了较强的鲁棒性。

Considering the inherent nonlinear kinematic performance of electro-hydraulic posi- tion servo systemt,a fuzzy adaptive controller which-simulates human intelligence is designed.The controller is simple at algorism and easy at imple- mentation.Computer simulation and experimental results show the method can imperove positioning accuracy considerably and can effective overcome the influence of nonlinearity.Furthermore,the con- troller is insensitive to variation in reference mod- el.
