【摘要】：感应耦合电能传输（InductivelyCoupled Power Transfer, ICPT）技术是一种新兴的无线电能传输技术，这种技术基于法拉第电磁感应原理，克服了传统导线电能传输方式的诸多缺陷和不足，是一种具有广阔应用前景的电能传输技术。为实现感应耦合电能传输系统稳定、高效地运行，必须保证系统工作在完全谐振状态，所以通常需要在感应耦合电能传输系统中加入谐振补偿。但是系统输出负载、耦合系数和其他环境因素的改变会导致系统固有谐振频率发生漂移，从而导致系统失谐，所以有必要引入感应耦合电能传输系统的实时调谐控制策略，本文正是围绕感应耦合电能传输系统的谐振工作状态、谐振判定方法和调谐控制策略的研究展开的。论文通过分析采用谐振补偿的感应耦合电能传输系统的多软开关工作点现象对传统谐振判定方法——逆变电路输出阻抗角检测法，及基于锁相环的跟踪调谐策略、基于补偿电容矩阵的调谐策略以及基于相控电感的调谐策略的干扰的研究，证明了传统谐振判定方法的局限性，并改进一种基于能量流的感应耦合电能传输系统谐振判定方法，以克服多软开关工作点现象对谐振判定的影响。以基于能量流的感应耦合电能传输系统谐振判定方法的研究为基础，改进一种基于分段Bang-Bang控制的调谐策略对感应电能传输系统进行调谐。而对于这种调谐控制策略应用在采用混联谐振补偿拓扑的感应耦合电能传输系统中时，调谐效果不够理想的问题，以基于能量流的ICPT系统谐振判定方法为基础，提出一种基于模糊控制的调谐控制策略，将其应用在采用混联谐振补偿拓扑的感应耦合电能传输系统中，以实现不同谐振补偿拓扑结构的感应耦合电能传输系统的高效调谐。通过MATLAB仿真软件，对这两种基于感应耦合电能传输系统调谐控制策略进行仿真研究，并搭建实验平台进行实验，，以验证其可行性、准确性和高效性。
[Abstract]:Inductively coupled Power transfer (ICPTT) is a new radio energy transmission technology. Based on Faraday electromagnetic induction principle, this technology overcomes many defects and shortcomings of traditional electric power transmission mode. In order to realize the stable and efficient operation of the induction coupled power transmission system, it is necessary to ensure that the system works in a fully resonant state. Therefore, it is usually necessary to add resonance compensation to the induction coupled power transmission system, but the change of the output load, coupling coefficient and other environmental factors will lead to the shift of the inherent resonance frequency of the system. Therefore, it is necessary to introduce the real-time tuning control strategy of induction coupled power transmission system. This paper focuses on the resonant working state of induction coupled power transmission system. The resonant decision method and tuning control strategy are studied. By analyzing the multi-soft switching working point phenomenon of inductively coupled power transmission system with resonant compensation, this paper analyzes the traditional resonance determination method-the method of detecting the output impedance angle of inverter circuit. The research of tracking tuning strategy based on phase-locked loop, tuning strategy based on compensating capacitance matrix and interference of tuning strategy based on phase-controlled inductor proves the limitation of traditional resonance judgment method. An energy flow-based resonant decision method for induction coupled power transmission system is improved to overcome the influence of multi-soft switching operating point phenomenon on resonance determination. Based on the research of resonance determination method of induction coupled power transmission system based on energy flow. An improved tuning strategy based on piecewise Bang-Bang control is proposed for tuning induction power transmission systems. This tuning strategy is applied to inductively coupled power transmission with hybrid resonant compensation topology. In the system. In order to solve the problem that the tuning effect is not ideal, a tuning control strategy based on fuzzy control is proposed based on the resonance decision method of ICPT system based on energy flow. It is applied to inductively coupled power transmission system with hybrid resonant compensation topology. In order to realize the efficient tuning of induction coupled power transmission system with different resonant compensation topology, the simulation software MATLAB is used. The two tuning control strategies based on induction coupled power transmission system are simulated and the experimental platform is built to verify their feasibility accuracy and efficiency.
