| Abstract: | 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.. |
