摘　　要：本文解决两相交流电源供电下二维全向无线充电信息物理融合系统的能量传输效率优化问题,发现了系统的频率分叉现象及其能量传输机理,利用混成自动机理论建立了系统的形式化模型.制定了一种面向不同负载区间的多供电模式的最优输电控制策略和能量传输频率优化算法.论文对共振条件下的频率分叉现象进行仿真实验,验证了两相交流电源供电下能量的最优传输理论模型,可用于电动汽车、智能手机等移动装置的充电系统.This paper solves the problem of optimization of energy transmission efficiency in the two dimensional omnidirectional charging cyber physical system(2 DOWC-CPS) with two phase alternating current(AC) power supply,the frequency bifurcation and energy transmission mechanism are found,and a formal model of the system is established by using hybrid automata theory.An optimal transmission control strategy adopting different power supply modes when the load is in different intervals determined by the characteristic parameters of the physical coils is put forward,and a reactive algorithm based on the optimal control strategy is also developed to carry out the frequency optimization of energy transmission efficiency.It simulates the frequency bifurcation phenomenon under resonant condition,and verifies the optimal transmission theory model under two-phase AC power supply.So,it provides an application reference for mobile charging including electric vehicles and smart phones.
