摘　　要：针对目前无线充电产品大多只能在固定位置下工作的问题,提出了一种可以在有效范围中实现输出电压可控和传输效率最大化的磁耦合谐振无线电能传输系统控制器设计方案。分析了系统拓扑结构,并确定了更适合高频无线电能传输系统的脉冲密度调制技术。设计了一种由模型预测控制和粒子群寻优算法结合组成的控制器。在MATLAB/Simulink上进行了仿真,结果表明所提出的控制器在动态和稳态下均具有优秀的控制效果。Aiming at the problem that most of the current wireless charging products can only work in a fixed position,a controller design scheme for a magnetically coupled resonant wireless power transmission system that can control the output voltage and maximize the transmission efficiency within the effective range is proposed.The system topology is analyzed,and the pulse density modulation technology that is more suitable for high-frequency wireless energy transmission systems is determined.A controller composed of model predictive control and particle swarm optimization algorithm is designed.Simulations were carried out on MATLAB/Simulink,and the results can show that the proposed controller has excellent control effects in both dynamic and steady states.
