Presented is a harmonic regulator that regulates a plurality of individual harmonics in a system having periodic torque disturbances to commanded values, including zero. For each harmonic being regulated, a feedback signal having at least one harmonic component due to the harmonic being regulated is transformed from a source reference frame to a harmonic reference frame of the harmonic being regulated to form a qd feedback signal. The qd feedback signal is subtracted from the commanded value to form a qd signal and regulated. The regulated qd signal is transformed to a destination reference frame to form a compensation signal and the compensation signal is added to a control signal to form a qd control signal that drives each harmonic being regulated towards the commanded value.

L'invention concerne un régulateur d'harmoniques qui régule une pluralité d'harmoniques individuelles dans un système ayant des perturbations de couple périodiques à des valeurs commandées, y compris zéro. Pour chaque harmonique qui est régulée, un signal de rétroaction ayant au moins une composante harmonique due à l'harmonique qui est régulée est transformé à partir d'une trame de référence source vers une trame de référence harmonique de l'harmonique qui est régulée pour former un signal de rétroaction qd. Le signal de rétroaction qd est soustrait de la valeur commandée pour former un signal, puis régulé. Le signal qd régulé est transformé en une trame de référence de destination pour former un signal de compensation, et le signal de compensation est ajouté à un signal de commande pour former un signal de commande qd qui entraîne chaque harmonique qui est régulée vers la valeur commandée.
