| Abstract: | According to the composition of cylinder electro-hydraulic servo system,the mathematical model of cylinder has been established,and the closed-loop transfer function of valve control cylinder system is obtained by system identification method.The mathematical model to approximate the optimal control is based on the full state feedback theory.The simulation results show that the controller has the pole placement of hydraulic position servo system,completed the optimization target and prove the tracking accuracy of the hydraulic servo system with full state feedback control and the feasibility of the project. |
