HARMONIC DISTURBANCE REGULATOR

摘要

Presented is a harmonic regulator that regulates a plurality of individua l harmonics in a system having periodic torque disturbances to commanded val ues, including zero. For each harmonic being regulated, a feedback signal ha ving at least one harmonic component due to the harmonic being regulated is transformed from a source reference frame to a harmonic reference frame of t he harmonic being regulated to form a qd feedback signal. The qd feedback si gnal is subtracted from the commanded value to form a qd signal and regulate d. The regulated qd signal is transformed to a destination reference frame t o form a compensation signal and the compensation signal is added to a contr ol signal to form a qd control signal that drives each harmonic being regula ted towards the commanded value.
