摘　　要：建立电液位置控制系统的数学模型,设计H∞混合灵敏度控制器,利用MATLAB/Simulink进行系统的PID控制和H∞混合灵敏度控制的仿真,最后通过变负载实验对PID控制、H∞混合灵敏度控制效果进行比较。仿真和实验结果表明,H∞混合灵敏度控制比常规PID控制具有更好的鲁棒性,可以很好地满足大多数电液位置控制系统的要求,具有很强的实用性。The mathematics model of electro-hydraulic control system was set up. H∞ mixed sensitivity controller was designed. The simulations of PID control and H∞ mixed sensitivity Control of the system were made based on MATLAB/Simulink. The control effect of PID control was compared with that of H∞ mixed sensitivity control through variable load experiments. The simulation and experimental results show that the robustness of H∞ mixed sensitivity controller is better than that of conventional PID controller. H∞ mixed sensitivity controller can satisfy the control request of electro-hydraulic control system which is much applied.
