【摘要】：感應(yīng)耦合電能傳輸技術(shù)（Inductively Coupled Power Transfer，簡稱ICPT）是一種新型的電能傳輸技術(shù)，它通過感應(yīng)耦合方式向負(fù)載提供電能，以其安全、環(huán)保、低維護(hù)、適應(yīng)性強(qiáng)等優(yōu)點(diǎn)得到了迅速的發(fā)展。 近幾年，ICPT技術(shù)在實際應(yīng)用中取得了諸多的成功案例，其廣闊的應(yīng)用前景得到了展示。人們對傳統(tǒng)ICPT技術(shù)相關(guān)理論及其設(shè)計方法和控制問題進(jìn)行了較為深入的研究分析，這些研究成果對實際應(yīng)用有著良好的指導(dǎo)作用。但是這些應(yīng)用和研究多是針對單對單的磁耦合結(jié)構(gòu)展開的，在面臨多拾取端多負(fù)載的應(yīng)用場合時，這些研究成果雖然也有著一定的指導(dǎo)作用，但是卻不能更深入的指導(dǎo)實踐。本文主要對多拾取端ICPT系統(tǒng)的磁路結(jié)構(gòu)和穩(wěn)壓輸出控制方法展開分析與研究，在不增加系統(tǒng)輸入電源的容量的前提下，實現(xiàn)穩(wěn)壓輸出的控制要求。 本文以多拾取端ICPT系統(tǒng)為研究對象，，主要工作包括以下幾點(diǎn)： ①在已有的研究基礎(chǔ)上，分析常用磁路結(jié)構(gòu)適合的應(yīng)用場合，給出了一種適用于帶氣隙互感電路的M值的測量方法以及K值和線圈電感的計算方法。并通過Maxwell軟件對文中提到的新型磁路結(jié)構(gòu)進(jìn)行仿真，選取最優(yōu)的空間擺放位置。仿真結(jié)果表明新型磁路結(jié)構(gòu)可以很好的提高系統(tǒng)拾取電能的能力。 ②針對系統(tǒng)的輸出穩(wěn)定性分別從拓?fù)浣Y(jié)構(gòu)和副邊電路兩方面出發(fā)，對系統(tǒng)的工作原理進(jìn)行詳細(xì)解析，選取適當(dāng)?shù)闹C振模型和補(bǔ)償結(jié)構(gòu)，并設(shè)計適合該系統(tǒng)的穩(wěn)壓輸出控制策略，從理論上對比分析了這些算法的穩(wěn)壓效果和應(yīng)用范圍。 ③通過Matlab/Simulink平臺針對文中給出的多拾取端ICPT模型，主要圍繞PID控制算法和智能分段控制算法進(jìn)行仿真，得到了較為理想的穩(wěn)壓輸出效果，對控制算法的有效性進(jìn)行了驗證。 ④在已有條件下對多拾取端ICPT系統(tǒng)的理論研究和仿真結(jié)果進(jìn)行實驗驗證。實驗結(jié)果表明本文設(shè)計的多拾取端ICPT系統(tǒng)在負(fù)載變化的情況下具有較好的穩(wěn)定性，并驗證了輸出控制策略能夠滿足輸出電壓穩(wěn)定性的需求。
[Abstract]:Inductively coupled power transmission technology (Inductively Coupled Power Transfer, (ICPT) is a new type of power transmission technology, which provides electric energy to load through induction coupling. It has been developed rapidly because of its safety, environmental protection, low maintenance, strong adaptability and so on. In recent years, ICPT technology has achieved many successful cases in practical application, and its broad application prospect has been shown. People have carried on the thorough research and analysis to the traditional ICPT technology related theory and its design method and the control problem, these research results have the good guidance function to the practical application. However, most of these applications and studies are aimed at single magnetic coupling structures. in the face of multi-pickup and multi-load applications, although these research results also have a certain guiding role, they can not guide the practice more deeply. In this paper, the magnetic circuit structure and voltage stabilizing output control method of multi-pickup ICPT system are analyzed and studied, and the control requirements of stable voltage output are realized without increasing the capacity of the input power supply of the system. In this paper, the multi-pickup ICPT system is taken as the research object, the main work includes the following points: 1 on the basis of the existing research, the suitable applications of common magnetic circuit structure are analyzed, and a measurement method of M value suitable for air gap mutual inductance circuit and the calculation method of K value and coil inductance are given. The new magnetic circuit structure mentioned in this paper is simulated by Maxwell software, and the optimal spatial placement is selected. The simulation results show that the new magnetic circuit structure can improve the ability of the system to pick up electric energy. (2) according to the output stability of the system, the working principle of the system is analyzed in detail from two aspects of topological structure and auxiliary circuit, the appropriate resonance model and compensation structure are selected, and the voltage stabilizing output control strategy suitable for the system is designed, and the voltage stabilizing effect and application range of these algorithms are compared and analyzed theoretically. 3 through the Matlab/Simulink platform for the multi-pickup ICPT model given in this paper, the PID control algorithm and intelligent piecewise control algorithm are mainly simulated, and the ideal voltage stabilization output effect is obtained, and the effectiveness of the control algorithm is verified. (4) the theoretical research and simulation results of multi-pickup ICPT system are verified by experiments under the existing conditions. The experimental results show that the multi-pickup ICPT system designed in this paper has good stability under the condition of load change, and it is verified that the output control strategy can meet the requirements of output voltage stability.
