Practical modi cations of a repetitive-based controller aimed to compensate 6ℓ ± 1 harmonics Conference Paper uri icon

abstract

  • In this paper, a modi ed repetitive-based scheme for the compensation of 6ℓ ± 1 harmonic components is proposed. The proposed modi cations are aimed to alleviate the phase shift caused by, rst, the introduction of the damping gain, which were introduced to limit the in nite gain produce by the controller, and, second, the introduction of auxiliary low pass lters, which were intended to restrict the bandwidth of the controller and to reinforce the stability when the controller is installed in a closed-loop system. Experimental results on a digital implementation are provided to illustrate the bene ts of the modi ed scheme. © 2008 IEEE.
