Abstract
A method of reducing mechanical vibrations of a motor system including an electric motor, the method including: a) receiving a vibration-related signal based on measurements by one or more sensors mounted on the electric motor, b) generating a reactive torque reference based on the vibration-related signal, and c) controlling the electric motor based on the reactive torque reference and a main torque reference to counteract the mechanical vibrations.
