摘　　要：从张力/速度控制目标出发,分析了钢丝绳绞车张力/速度控制系统的结构原理.通过调节溢流阀开口大小,改变液压马达进出口的压差实现对其输出扭矩的电液比例控制。在具体控制实现方式上选择工控机作为控制器,通过张力,速度传感器实现对钢丝绳主动释放过程中的张力和速度的闭环控制。Electro-hydraulic proportional control methods are applied to control the export tension of the hydraulic motor and also the related winding machine by modifying the pressure difference between inlet and outlet of the hydraulic motor on purpose of gettingfit tension and velocity for steel wire, the industrial computer is choosed as the controller in order to realize the tension and velocity control as well as the tension and velocity sensors .

关 键 词：工控机 张力控制 速度控制 电液比例控制
