The tripping of drive systems in process industries are caused due to voltage sag or swell, which results in heavy economic losses. As a solution to this, DVR is reported. By using PI-controller for the control of DVR, a noticeable steady state error is found. But the analysis shows that there is a limitation in giving higher value of gain for the PI-controller, as it magnifies the resonant frequency components. This paper deals with the performance improvement in DVR operation by using PR-controller. Simulation results of the DVR output voltage with PI and PR controllers are depicted and experimental validation of the proposed PR controller is done.
