Research on Robust Control Based on Model Reference Fuzzy Adaptive of an Electrohydraulic Position Servo System

针对电液位置伺服系统存在的参数变化及外力扰动 ,引入模型参考模糊自适应机构 ,构成模型参考模糊自适应控制 ,即MRFAC ,仿真实验表明 ,与传统PID相比 ,该方法可以有效抑制参数扰动及外力干扰 。

Since electrohydraulic position servo system is often subjected to unknown disturbances, and the system parameters are deviated as the environment varies, a model reference fuzzy adaptive control (MRFAC) method is proposed. The simulation results show that the controller can moderate the unknown and time-varing external load disturbances effectively, and has much better response characteristics than that of conventional constant PID controller..
