Abstract Aimed at the charging control of contactless power transfer (CPT) systems, the paper proposes a
primary side control method based on H∞ control. With the conversion of differential dynamic model in frequency
domain, the generalized state space averaging model is set up. The control system structure and performance
weighted function are proposed. The Ricatti equations for controller and observer are put forward and solved with
Hermitian matrix as well. Furthermore, an puting method is designed to acquire optimal H
controller. The control method can regulate the energy injection according to different load condition and improves
