Abstract
A method is provided for controlling the current intensity of the electric current flowing through an inductive consumer, the consumer being connected in series to a switching device and a current measuring unit, and in parallel to a free-wheeling element, and the switching device being activated for adjusting the current intensity during a pulse width modulation period. It is provided that a mean load voltage to be set during the pulse width modulation period is determined from an input current intensity with the aid of a first controller, the mean load voltage being set in the pulse width modulation period with the aid of the switching device at the consumer, the mean load voltage or a setpoint load voltage determined with the aid of a second controller from a predefined setpoint current intensity being fed to a model adapted to the consumer, and the input current intensity being ascertained from the difference between the predefined setpoint current intensity and a difference variable between an actual current intensity through the consumer and a model current intensity determined with the aid of the model. A circuit configuration for implementing the method is also provided.
