Active Damping by State Feedback Control in Induction Motor Drive with Filter

Abstract

The use of passive LC filters affects the dynamics of rotor-flux-oriented controlled induction motor drive with the inverter output filter. Therefore, a combined control technique has been proposed in this paper, where the state variables of the filter and motor have been controlled using the state-feedback controller and proportional-integral controllers, respectively. The proposed technique has been analyzed and simulation results have been provided for validation.
