A Linear Valve Actuated Switched Inertance Hydraulic System

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

A Switched Inertance Hydraulic System (SIHS) makes use of a switching element, a hydraulic capacitance
and an inertance in order to achieve theoretically lossless control of hydraulic flow and pressure. This paper
reports on experimental results of a SIHS which is set up to control pressure and makes use of a novel linear
valve as its switching element. The control and dynamic performance of this valve are characterised before
presenting experimental results of the flow booster circuit. It was found that the SIHS worked as expected at
a limited range of switching widths and frequency before a failure within the instrumentation precluded
experimentation on a wider range of conditions.
