【摘要】：感應(yīng)耦合電能傳輸（InductivelyCoupled Power Transfer, ICPT）技術(shù)是一種新興的無線電能傳輸技術(shù)，這種技術(shù)基于法拉第電磁感應(yīng)原理，克服了傳統(tǒng)導(dǎo)線電能傳輸方式的諸多缺陷和不足，是一種具有廣闊應(yīng)用前景的電能傳輸技術(shù)。為實(shí)現(xiàn)感應(yīng)耦合電能傳輸系統(tǒng)穩(wěn)定、高效地運(yùn)行，必須保證系統(tǒng)工作在完全諧振狀態(tài)，所以通常需要在感應(yīng)耦合電能傳輸系統(tǒng)中加入諧振補(bǔ)償。但是系統(tǒng)輸出負(fù)載、耦合系數(shù)和其他環(huán)境因素的改變會導(dǎo)致系統(tǒng)固有諧振頻率發(fā)生漂移，從而導(dǎo)致系統(tǒng)失諧，所以有必要引入感應(yīng)耦合電能傳輸系統(tǒng)的實(shí)時調(diào)諧控制策略，本文正是圍繞感應(yīng)耦合電能傳輸系統(tǒng)的諧振工作狀態(tài)、諧振判定方法和調(diào)諧控制策略的研究展開的。 論文通過分析采用諧振補(bǔ)償?shù)母袘?yīng)耦合電能傳輸系統(tǒng)的多軟開關(guān)工作點(diǎn)現(xiàn)象對傳統(tǒng)諧振判定方法——逆變電路輸出阻抗角檢測法，及基于鎖相環(huán)的跟蹤調(diào)諧策略、基于補(bǔ)償電容矩陣的調(diào)諧策略以及基于相控電感的調(diào)諧策略的干擾的研究，證明了傳統(tǒng)諧振判定方法的局限性，并改進(jìn)一種基于能量流的感應(yīng)耦合電能傳輸系統(tǒng)諧振判定方法，以克服多軟開關(guān)工作點(diǎn)現(xiàn)象對諧振判定的影響。 以基于能量流的感應(yīng)耦合電能傳輸系統(tǒng)諧振判定方法的研究為基礎(chǔ)，改進(jìn)一種基于分段Bang-Bang控制的調(diào)諧策略對感應(yīng)電能傳輸系統(tǒng)進(jìn)行調(diào)諧。而對于這種調(diào)諧控制策略應(yīng)用在采用混聯(lián)諧振補(bǔ)償拓?fù)涞母袘?yīng)耦合電能傳輸系統(tǒng)中時，調(diào)諧效果不夠理想的問題，以基于能量流的ICPT系統(tǒng)諧振判定方法為基礎(chǔ)，提出一種基于模糊控制的調(diào)諧控制策略，將其應(yīng)用在采用混聯(lián)諧振補(bǔ)償拓?fù)涞母袘?yīng)耦合電能傳輸系統(tǒng)中，以實(shí)現(xiàn)不同諧振補(bǔ)償拓?fù)浣Y(jié)構(gòu)的感應(yīng)耦合電能傳輸系統(tǒng)的高效調(diào)諧。通過MATLAB仿真軟件，對這兩種基于感應(yīng)耦合電能傳輸系統(tǒng)調(diào)諧控制策略進(jìn)行仿真研究，并搭建實(shí)驗(yàn)平臺進(jìn)行實(shí)驗(yàn)，，以驗(yàn)證其可行性、準(zhǔn)確性和高效性。
[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.
