Research of Parameter Recognition on Electro-hydralic Servo System

Based on the nonlinearity and uncertainty of electro-hydralic servo system,system identitication method was propsed to carry out process identification of electro-hydralic servo system parameter.This method can change the nonlinear influence of system model to the system minimum error control,so the influence caused by nonlinear and undefined factor is reduced greatly,and the control accuracy and robutness of electro-hydralic servo system is enhanced.
