Abstract: Embodiments of the present invention relate to an a method, apparatus and computer program product for controlling the operation of a drive unit comprising a plurality of switching modules arranged to receive a DC electricity supply and generate an AC electricity supply for driving a load from the received DC electricity supply, the AC electricity supply being generated by the switching of the plurality of switching modules between a conducting state and a non-conducting state. The method comprises receiving one or more characteristics associated with each of the switching modules, comparing, for each switching module of the plurality of switching modules, a characteristic of the switching module with an equivalent characteristic associated with one or more other switching modules of the plurality of switching modules, and controlling a time period during which one or more of the plurality of switching modules are in the conducting state in accordance with a result of the comparison.

Abstract: A method of reducing periodic disturbances in the feedback quantity of a controlled system is disclosed. The method includes receiving a feedback signal and repeatedly deriving respective magnitudes of harmonic components of the feedback signal to produce corresponding error signals. The error signals and harmonic components are used to generate harmonic control signals. The harmonic control signals are used to create a plurality of negative feedback loops acting to reduce the error signals. The present disclosure thus provides negative feedback control in the frequency domain. In one specific disclosed embodiment, the control is tied to the periodic domain resulting from the rotation of an actuator motor shaft.
