1996•asmedigitalcollection.asme.orgThis study develops closed-form equations that may be used to guide the up-front design of
a variable-displacement pump. In particular, the initial design of the control actuation system
and the controller flow-gain is considered. A dynamic model of the pumping system is also
presented and the dynamic effect of parameter variations such as actuator volume,
discharge-hose volume, controller flow-gain and system leakage is discussed.
