Electro-Hydraulic Control Techniques and Applications of Launching Systems

In this paper, an electro-hydraulic servo control buffer device is proposed. Its dynamic characteristics are analyzed and the equation of motion is established, and the adaptive robust controller is derived according to the robust adaptive law. The simulation results by Matlab show that the control strategy designed can achieve good results. The work done in this paper can be used as a reference for the design of hydraulic cylinder controller of buffer device. It can be especially used in missile ejection device and carrier aircraft ejection device, which need to use hydraulic cylinder to realize buffer system.
