Abstract
Successful application of digital fluid power displacement pumps rely on proper control of the actively controlled high pressure and low pressure manifold valves. This paper concerns a method, where the valve timing control and the overall displacement modulation are separated. The displacement chambers of the pump are operated in full-stroke mode and a pulse density modulation method is used to approximate a desired displacement output. This pulse density modulation is performed with delta-sigma modulation, whereby the chamber activation pattern is determined. The method is implemented in a simulation model of a digital hydraulic pump in order to exemplify the use of it.
