Method for controlling the supply of electrical energy to an electromagnetic device and use of a sliding mode controller. Control devices are known in which, in order to obtain a desired movement of an electromagnetically activated gas exchange valve, the supply of electrical energy is controlled as a function of a measured position of the gas exchange valve. The novel method is intended to optimize the control with respect to the movement forms to be obtained, the formation of noise and/or the required use of electrical energy. In a control device according to the invention, a differential signal is generated using the movement signal or a signal generated from the movement signal, and using a desired signal. The supply of electrical energy to the activating device of the gas exchange valve is controlled by means of a sliding mode controller using the differential signal.
