Integrated Component Fluidic Servovalves and Position Control Systems

Abstract

The operating characteristics of fluidic laminar proportional amplifier (+PA's) operating on hydraulic oil have been determined as a function of pressure and temperature. The useful operating range of these elements has been defined for application in multistage gain blocks and summing amplifiers. An operational servovalve constructed from LPA's has been developed and coupled with a fluidic position feedback transducer, summing amplifier and ram to construct a closed loop position control system. Static and dynamic experimental evaluation of the servosystem has shown that its performance is comparable to that of a servo employing electrohydraulic components. This development effort has demonstrated the capability to develop high performance, closed loop servo components from standard, integrated component fluidic elements. (Author)
