【摘要】：目前感应式无线电能传输(inductive power transfer,IPT)系统电磁耦合机构的设计往往是追求单目标或者是多随机目标的设计准则,这导致了电磁耦合机构设计的非全局性优化品质问题。针对该问题,文章首先提出电磁耦合机构的携能特性指标、空间特性指标及能效特性指标作为其综合性能评判的指标体系,在此基础上引入模糊综合评判方法,提出一种电磁耦合机构综合性能评判方法,对满足同一应用需求的多种类型电磁耦合机构进行评价,并得到具体、直观的数值评价结果,为耦合机构类型的确定提供参考。文章对以电动汽车无线充电系统的电磁耦合机构为例,通过层次分析法推导得到具有目标权重的性能特性指标的表述,并应用提出的评判方法对两种类型电磁耦合机构的综合性能进行评判,得到具体的数值评判结果。最后通过实验验证理论分析的合理性。
[Abstract]:At present, the design of electromagnetic coupling mechanism of inductive radio energy transmission (inductive power transfer,IPT) system is usually based on the design criterion of single target or multiple random targets, which leads to the non-global optimization quality problem in the design of electromagnetic coupling mechanism. Aiming at this problem, this paper first puts forward the energy carrying characteristic index, the spatial characteristic index and the energy efficiency characteristic index of electromagnetic coupling mechanism as the index system of its comprehensive performance evaluation. On this basis, the fuzzy comprehensive evaluation method is introduced. This paper presents a comprehensive performance evaluation method for electromagnetic coupling mechanism, which evaluates various types of electromagnetic coupling mechanism which meet the same application requirements, and obtains concrete and intuitive numerical evaluation results, which provides a reference for determining the type of coupling mechanism. Taking the electromagnetic coupling mechanism of the wireless charging system of electric vehicle as an example, this paper deduces the expression of the performance characteristic index with target weight by analytic hierarchy process (AHP). The comprehensive performance of the two types of electromagnetic coupling mechanisms is evaluated by the proposed evaluation method, and the concrete numerical evaluation results are obtained. Finally, the rationality of the theoretical analysis is verified by experiments.
