 Abstract
 A Study on Robust Tracking Control of a Three-phase Bidirectional Charger for Electric Vehicle Chivon Choeung (Supervised by Professor Young-Il Lee) Department of Electrical and Information Engineering Graduate School Seoul National University of Science and Technology This thesis presents a robust control strategy of a three-phase off-board bidirectional AC-DC battery charger for electric vehicle. The conventional constant current (CC) and constant voltage (CV) charging mode is considered to provide a fast charging performance for the batteries. The bidirectional charger also allows to use the full electric vehicle as an energy storage system for the electric grid, charging the in the peak-off times and delivering the energy back to the grid in peak times of electrical consumption. In discharging mode, the bidirectional charger maintains constant active power flow to grid with a given reference. The proposed control consists of inner-loop robust control and outer-loop conventional PI control. For the inner-loop robust control, a state feedback controller with integral action is employed in dq-synchronous frame. The set of stabilizing gains of this controller are determine by a Linear Matrix Inequality (LMI)-based optimization so that the convergence time to steady stead is minimized in the occurrence of the parametric uncertainties of the L-filter. The efficacy of the proposed controller is verified through simulation and experimental results on 102.4V Lithium iron phosphate (LiFePO4) batteries.
