Zusammenfassung:	A pump system includes a pressure compensator and a speed compensator for controlling the displacement of a variable displacement pump having an inlet and an outlet. The variable displacement pump is driven by a drive shaft powered by an electric motor. The pressure compensator adjusts the displacement of the variable displacement pump based on a pump pressure at the pump outlet. The speed compensator adjusts a maximum magnitude of the displacement of the variable displacement pump based on a speed of the electric motor.
