Research on Predictive Control of DC/DC Converter for Dynamic Wireless Charging System

Abstract

Electric vehicles (EV) are the future direction of automotive development, and dynamic wireless charging (DWC) system can effectively solve the difficulty of charging and improve the deficiency in mileage. Therefore, the technology of DWC is an ideal choice for charging electric vehicles. This paper presents the design and analysis of DWC system, and analyses the selection of DC/DC converter and controlled variables. In this study, model predictive control (MPC) is proposed to control DWC system accurately, and MPC is compared with dual loop PID control. Simulation results demonstrate the correctness and effectiveness of the proposed MPC controller in dynamic wireless charging system.
