For the influence of time varying parameter on servo accuracy of electro-hydraulic position servo system, nonlinear robust adaptive controller with the ability of restraining the parameter perturbation for symmetry valves-control symmetry cylinder system is put forward which is based on the Lyapunov stability theory, The nonlinear state equation of symmetry valves-control symmetry cylinder system was derived, and the controller design process was given. the control strategy was verified on Co-simulation of MATLAB & AMESim and semi-physical simulation platform respectively, the simulation and experimental results show that the tracking performance of electro-hydraulic position servo with nonlinear robust adaptive controller meet the double ten index, and verify efficiency of the method presented through simulations.
