ABSTRACT

A nonlinear state feedback controller is proposed to stabilise the output current of the wireless charging system for unmanned surface vehicles in response to the unstable charging and high waste of power resources caused by mutual inductance changes during the wireless charging process of unmanned surface vehicles. Firstly, the output characteristics of the wireless charging system with LCC-S topology are analysed and its mathematical model is established. Secondly, a state feedback controller is designed to control the output current of the wireless charging system of unmanned surface vehicles. Finally, a simulation model is built in Mtalab to verify the correctness of the control strategy. The simulation results show that the actual output current of the wireless charging system for unmanned vehicles can be quickly stabilised and kept constant under the change of mutual inductance. It also provides some reference for the research of optimal control method of wireless charging system for unmanned surface vehicles.
