This schematic diagram shows a model of a hydraulic cylinder. The model directs the pump flow, Q, to supply pressure, p1, from which the laminar flow, q1ex, leaks to exhaust. The control valve for the piston/cylinder assembly is modeled as turbulent flow through a variable-area orifice. ...
A hydraulic pump control system is shown that can control the absorbing torque of a hydraulic pump with respect to the engine power for driving the hydraulic pump in a well-balanced manner, and reduce a deviation of an actual revolution number from a target revolution number of the engine. A...
