The success of digital hydraulics is dependent on the ability to produce digital hydraulic valves that can supply both high flows and high switching rates. This paper will elucidate the control scheme of; and results obtained from; such a valve which has been developed at the University of Bath. It will be shown that through the combination of iterative learning control and state variable feedback control it is possible to accurately follow a 100Hz PWM signal on a valve designed for high flow rates (65l/min at 10bar); making it well suited to use in a Switched Reactance Hydraulic Transformer
