Suppression of Harmonic Current for IPMSM using Generalized Repetitive Control

抄録

Interior permanent magnet synchronous motors (IPMSMs) are generally driven by current control based on a vector control system. Usually, in such a system, the harmonic current appears in the current control loop. Some harmonic current suppression control methods using repetitive control have been proposed. In earlier repetitive control techniques, the amount of memory for implementation was not considered explicitly. Furthermore, optimality was not ensured in our earlier studies. In this paper, we present a novel harmonic current suppression method using the generalized repetitive control. Compared with the conventional method, the proposed method achieves better control performance while taking into account the amount of memory for implementation. The effectiveness of the proposed method is verified through simulations and experiments.
