Regulating method for a volume control

In a regulating method for controlling an electrical actuator, especially a valve for regulating a volume flow in an injection system for an internal combustion engine, a nominal value is set for an actuating variable of the actuator; the actuator is controlled by a pulse width-modulated electrical control signal with a pre-defined pulse duty factor and a pre-defined period for adjusting the desired nominal value of the actuating variable; a flow threshold value is determined according to the pre-defined nominal value for the actuating variable; the flow flowing through the actuator is continuously measured during the control by the control signal and before the end of the period; the measured flow is compared with the flow threshold value/and the flow flowing through the actuator is switched off before the end of the period of the control signal if the measured flow exceeds the current threshold value.
