Abstract: A method for regulating the current through an electromagnetic actuator. The actuator, a first switch and a current-measuring circuit form a series circuit. A free-wheeling diode is parallel-connected to the actuator. The first switch is closed and opened by a control and a pulse generator using a PWM signal (PWM=pulse width modulation) in such a way that the current flowing through the actuator and measured by the current-measuring circuit is regulated to a setpoint value (SW). The time duration of one on and off switching cycle of the PWM signal is altered, and a so-called dither function in the form of a low-frequency oscillation is superimposed on the PWM signal.

Abstract: The invention is directed to a method for balancing a current controller for controlling a current. The current controller is configured to adjust the current to a desired value of current while considering an actual value of the current determined by a measurement. The current controller is balanced while considering the deviation between the real magnitude of the current and the actual value applied to adjust the current.
