Adaptive Switching Control for Wireless Power Transfer Systems Based on Identification

This paper focuses on the application of switching control methods to wireless power transfer (WPT) systems. The method addresses the nonlinear perturbations introduced by the inverter by switching a set of controllers as well as weighting the outputs. Firstly, the internal model controllers (IMC) set is designed based on the nonlinear characteristics specific to WPT. Secondly, controller switching rules are developed to ensure the selection of the appropriate controller set across variations in phase shift angles. Finally, a controller set weighting function design scheme is explored, incorporating PID controllers with diverse tuning rules and dynamically adjusting their output-weighted multipliers to enhance closed-loop response. The effectiveness of the proposed method is validated by simulations and experiments, which further substantiate the performance and reliability of the method in practical applications.
