【Abstract】 Based on the high -speed on -off valve of PWM, the author designed two hydraulic synchronization control system. One is direct-control, and the other is pilot-control. Each of them has simple struc- ture and easy to integrate. All of them can realize high -precision displacement synchronous control.更多还原
