摘　　要：研究了一种带位置反馈的水压比例双缸同步控制系统.选择主从控制策略,其中主动缸采用分别布置于进出口的两个单向节流阀控制,从动缸采用两个水压比例流量阀控制,并建立了系统的数学模型.与此同时,建立了试验测试系统并将试验结果与仿真结果进行了对比.试验结果表明,采用PID控制方法同步控制精度达到2.5%,同时理论分析和试验结果具有很好的一致性.In this paper,a dual-cylinder water hydraulic synchronous system with position feedback was studied.A master-slave control strategy was selected in the system,in which the master cylinder was controlled by two manually variable throttle check valves respectively at the inlet and outlet of the cylinder and the slave cylinder was controlled by two proportional flow control valves.The mathematical mode of the system was built up and simulation carried out.At the same time,a test bench using tap water as the media was established.Experimental results were compared with the simulation results.An experimental synchronous precision about 2.5% was obtained by using an adaptive PID control method.
