Zusammenfassung:	A method for regulating output pressure of a hydraulic drive system by using a rotational speed as the actuating variable. The method includes determining a setpoint rotational speed main component of motor drive as a pilot control signal, determining an error rotational speed as a regulating deviation from a comparison of an actual pressure value of the hydraulic drive system and a setpoint pressure value of the hydraulic drive system and adjoining regulating amplifier, adding the determined setpoint rotational speed main component to the determined error rotational speed to create the setpoint rotational speed as the actuating variable, and converting the created setpoint rotational speed into an input rotational speed of the motor drive to drive the hydraulic drive system at the converted rotational speed in order to generate regulated output pressure of the hydraulic drive system which represents actual pressure value.
