Abstract :
A robust controller is designed based on the generalized mixed sensitivity with regard to the mutual-inductance uncertainty between coupling coils in dynamic inductive power transfer system to fulfill an output tracking control. A generalized state-space averaging model for a nominal series-series resonance IPT system is firstly established and the characteristic of mutual-inductance is obtained in FEM software. A linear fractional transformation of the nominal model and its uncertainty is discussed to generate a standard optimized problem. Simulation and practical experiment results are conducted to verify the performance of a closed-loop IPT system with the designed robust controller.
