In order to solve the key technology of one three-axis hydraulic motion simulator, modeling and simulation are deduced. The differential pressure balancing control algorithm is adopted to compensate the load defor-mation induced by the parameter asymmetry of hydraulic motor subsystems controlled by two-valve and the PID algorithm is used to improve the global performance of the system. The result of experiment shows that the project takes out the better dynamic and static performance. At last, the project is applied to one three-axis hydraulic mo-tion simulator successfully.
