In the paper, we research on a preparatory electro-hydraulic actuator product, using the simulation software AMESim to research work to analyze the system performance. We research position in closed loop servo actuator system, generally only considered the requirements of the position. While the speed trajectory and precision control did not do high demand. The position of the system by increasing the speed control strategy module, the system meets the requirements of the position. At the same time, we can achieve speeds start-up operation, stable operation and stopped operation of the three phases according to the requirement following a given trajectory; simultaneously can carry out detailed system performance analysis and research. Simulation results show that increasing position speed control strategy module of the system get very good effect. It can realize the speed control system and satisfy the system output displacement and speed steady-state performance and dynamic response.
