Suppression of Harmonic Current for IPMSM using Generalized Repetitive Control

Abstract

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.

In the case of the system of position-trajectory control, the trajectory can be changed easily by only setting the value of data register; this control system has the flexibility which the mechanical system does not have.…”

B-spline parametrized solution of robust PID control using the generalized KYP lemma

“…The common workaround is to introduce weighting functions to emphasize particular frequency ranges, but this complicates the design and generally increases the order of the resulting controller. Various approaches have been proposed to overcome these issues [3], [4], [5], [6], [7].…”
