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.

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