摘要

When the wireless power supply system adopts relay mode, the frequency parameters or load parameters of the system often change due to environmental temperature, mechanical system aging and other factors, thus reducing the system output power and energy transmission efficiency. In order to solve such problems, this article takes five-coil WPT circuit as an example to establish its generalized state space model. On this basis, a two-degree-of-freedom H∞ robust controller is designed to make the system meet the anti-parameter perturbation performance and fast track performance.
