流量控制伺服阀是一种基本的伺服阀,在恒定负载下,它所控制的流量正比于阀的输入电流。这种伺服阀的流量在不同程度上将受负载压力改变的影响,如图4所示。流量控制伺服阀的零位稳定性,仅仅需要考虑这个图形原点附近的区域,在这个区域中,负载对伺 Flow control The servo valve is a basic servo valve that controls the flow at a constant load proportional to the valve’s input current. This servo valve flow to varying degrees will be affected by the load pressure changes, as shown in Figure 4. Zero control of flow control servo valve stability, only need to consider the area near the origin of this graph, in this region, the load on the servo
