【Abstract】 According to the composition of asymmetric cylinder electro-hydraulic servo system, mathematical model of valve controlled asymmetric cylinder system has been studied, which leads to an electro-hydraulic servo system block diagram and a simulation system based on full state feedback.A state observer has been embedded in the controller to achieve the Second-Order Optimization. The simulation results show that the pole placement for the hydraulic position servo system has been accomplished by the controller, the optimization has been done and the feasibility of application of full state feedback control in the asymmetric cylinder electro-hydraulic servo system has been verified too. The method has the great engineering significance.更多还原
