摘要 

针对电动汽车动力电池组的变电压间歇充电的快速充电模式,提出一种基于H非线性控制器的SP型磁耦合谐振式无线电能传输(MCR-WPT)系统副边控制方法。该方法首先基于SP型MCR-WPT系统的数学模型分析其拓扑输出电压特性,确定副边控制策略,并针对副边DC-DC变换器设计H非线性控制器;然后利用多目标多约束算法(NSGA-Ⅱ)对实现变电压间歇充电的控制器参数进行自动寻优,有效提高了闭环系统的上升时间、稳态误差及对参数扰动的鲁棒性;之后,对Buck变换器进行抗干扰仿真和系统变电压间歇充电特性仿真,仿真结果证明系统能够实现变电压间歇充电,并具有强鲁棒性和良好的动态响应;最后,设计系统的输出特性实验,实验结果证明该文提出的H非线性控制器及其参数优化的有效性。

Abstract

Aiming at the fast charging mode of variable voltage intermittent charging for power battery packs of electric vehicle, a secondary control method based on H nonlinear controller for SP magnetic coupling resonance wireless power transfer (MCR-WPT) system was proposed. The output voltage characteristics of SP MCR-WPT system were analyzed based on its mathematical model. The control strategy on the secondary side was determined, and the H nonlinear controller for DC-DC converter on the secondary side was designed. A multi-objective and multi-constraint algorithm (NSGA-Ⅱ) was used to automatically optimize the controller parameters during variable voltage intermittent charging process. As the results, rise time, steady-state error and robustness of parameter disturbances in the closed-loop system are effectively improved. Then, the anti-jamming simulation of Buck converter and variable voltage intermittent charging characteristics simulation of the system were carried out. The simulation results show that the system can realize variable voltage intermittent charging, and has strong robustness and good dynamic response. Finally, the output characteristic experiment of the system was designed. The experimental results verify the effectiveness of the H nonlinear controller and its parameter optimization proposed in this paper.
