基于多目标优化算法的IPT系统谐振网络参数设计

传统IPT系统的谐振网络参数设计方法存在着低效、准确性差以及难以对具有多个设计目标的系统进行谐振网络参数设计等缺陷。首先提出了一种基于NSGA-Ⅱ多目标优化算法的谐振网络参数的设计方法,经一次运算即可得到多组满足系统设计目标的谐振网络参数值,克服了传统谐振网络参数设计方法的缺陷。以PP结构的IPT系统为例,把高电压增益和系统效率最优设计作为目标,设计出了最优谐振网络参数。仿真和实验结果表明,设计出的谐振网络参数能够满足系统需要。

Parameters Design for IPT System Based on NSGA-II Multi-objective Optimization Algorithm

The traditional parameter design method of the resonant network of the IPT (Inductive Power Transfer) system has the disadvantages of ineffi-ciency and low accuracy, and it is difficult to design the resonant network parameters when the system with multiple design requirements need to be satisfied. This paper proposes an efficient parameters design method using NSGA-II Multi-objective optimization algorithm. After once run, NSGA-II can get many sets of parameters, which can satisfy the requirement of system. Taking the IPT system with PP topology for example, we use NSGA-II to design parameters for the system. Results of simulation and experiment verify that the design parameters which is obtained by the optimization algorithm can satisfy the requirements of system.
