Abstract: A servo system for controlling the position of a control fin (16) on an air vehicle has a servo valve with two valve members (60 and 701 respectively for putting the outlet (56) in communication with a source (48) of pressure fluid or a vent (58) for the fluid. The outlet (56) is coupled to a fluid motor (102) for driving the fin (16). The position of the fin is fed back at (144) for comparison at (18) with a command signal so that any difference can be supplied at (98,100) for driving the valve members. A drive input member (74) can move to the right in Figure 1 to move the valve members (60) to open a port (64) or can move to the left so that the valve member (70) opens the port (72). 
     The valve members are normally pressure balanced when the valve seats are closed, so that a very low input force is sufficient to open the valve in one sense or the other. However, there is a feedback path (84) including a restriction (86) from the output (56) to a negative feedback balancing chamber (80) which experiences the pressure at (56) after a time delay so that the negative feedback is approximately related to the first derivative of the pressure at (56). The dynamic valve gain is arranged to decrease with increasing rate of change of input singal.
