Abstract: The point - to -potint control for valve controlled electrohydraulic position servo system is studied The simulated human intelligence controller and the speed - aoeleration feedback compensation simulated human intelligence controller are designed and tested by step response . The results show that, for the engineering background inthis study, the steady-state error is less than 0.3 mrad , the regulation time is less than200ms, no overshoot exists and the system has good robustness by using the speed- acceleration feedback compensation simulated human intelligence controller
