摘　　要：将压差反馈闭环控制方法成功地应用于比例阀性能测试试验台上,得到了某电液比例方向阀稳态流量特性测试的实测结果。该方法解决了电液比例方向阀稳态流量特性测试中保持阀压降恒定的问题。The pressure difference feedback closed loop control was applied in the performance testing of test -bed of electrohydraulic proportional valve, the actual testing result of the steady - state flow characteristic a electrohydraulic proportional valve was obtained. The method solved the problem of invariable pressure difference when the valve was tested,
