State Feedback Controller Design of Dynamic Wireless Power Transfer System

In this paper, a general flow of modeling and controller design for the dynamic Wireless Power Transfer (WPT) system is given to improve the starting speed and stability of the system. In this method, the WPT system is modeled by Generalized State Space Averaging (GSSA) method. A state feedback controller with mutual inductance estimation is designed for a wireless power transfer system of an electric vehicle based on the Buck of secondary side. This controller improved the system response speed and adaptable to dynamic systems. The simulation and preliminary experimental verification are carried out.
