  • Patent number: 11114971
    Abstract: In a method for controlling a drive motor of an actuator for actuating a valve, the power of the drive motor is supplied by pulse width modulated voltage controlled by a control frequency to adjust the actuator coupled to a valve into a desired position. The control frequency is changed such that a mixture of frequencies is produced. The control frequency is changed in steps. The frequencies of the mixture of frequencies are selected to be near the nominal control frequency. A drive motor of an actuator is provided that is controlled by the described method.
