摘　　要：介绍了一种机械反馈式比例阀的工作原理,通过对以该阀为控制元件的液压位置控制系统进行建模和仿真,分析了在改变阀的可调参数时,液压位置控制系统的性能变化状况,结果表明机械反馈式比例阀在液压位置控制系统中具有较好的控制性能。The operating principle of a mechanical feedback proportional valve is introduced. Through made the model of and simulated the hydraulic position control system which utilized mechanical feedback proportional valve as a control element, the perform- ance-changing property of the control system was analyzed when changing the adjustable parameters of valve. The results show that the mechanical-feedback proportional valve in the hydraulic position control system has preferable control properties.
