There is provided a method of controlling a power output of an inverter drive (22) operably connected via an electrical machine (16) to a component (18). The component (18) is arranged during operation to generate a variable force having one or more periodic frequency components. The method comprises determining the power output of the inverter drive (22); determining a difference between the power output and a reference power output; and controlling an output frequency of the inverter drive (22) as a function of the difference, so as to stabilise the power output during operation of the component (18). The invention may be used to help reduce the problem of lighting flicker, as encountered when an inverter drive operates on a pulsating load. |
