Abstract :
The research and development of a simple fly-by-wire (FBW) hydraulic actuator is described. The actuator incorporated a pair of two-position valves for fluid metering. The valves were designed for high response and were driven by a pulse-width-modulated control signal. The actuator was designed to have the nominal force, slew rate, and frequency response of an F-16 Horizontal Tail/Flaperon Integrated Servo Actuator (ISA) when operating with one hydraulic supply system. The simple actuator configuration demonstrated control characteristics and input/output performance characteristics that equal or exceed other FBW actuator configurations (particularly the characteristics of frequency response and threshold). The power input for the control valves (29 W at 100% modulation) is consistent with modern direct drive FBW analog control valve power requirements. The response time for the valves was satisfactory for the control of the actuator
