Abstract
Hydraulic actuators have traditionally found application in servo systems requiring high bandwidth, high power per unit mass, and permitting low overall energy efficiency, the presence of hydraulic oil, and a rather bulky power supply. This paper presents a theoretical, analytical and experimental study of controlled fluid recircultion around an actuator to provide a more energy efficient hydraulic servo system for motion control while retaining the traditional advantages.
