Abstract
A system for active control of noise and/or vibration includes an electric machine; at least one sensor for sensing at least one of noise and vibration in the machine and generating at least one of an audio signal representing noise and a vibration signal representing vibration; a controller obtaining at least one of the noise signal and the vibration signal, the controller generating control signals to reduce at least one of noise and vibration in the machine; and power electronics receiving the control signals and generating drive signals for the machine.
