Buck-Boost转换器转换周期轨道从混乱的状态,本文提出一种　　混沌控制方法通过改善电感电流和输出电压之间的关系。通过调整　　耦合强度,这种方法可以控制混沌周期2 Buck-Boost转换器,period-4,period-8轨道　　period-9轨道和周期3,时间6,不确定不稳定周期轨道(着)。-To transform the Buck-Boost converter　the chaotic state to the periodic orbits, this paper proposes a

chaotic control method by improving the correlation between the inductor current and the output voltage. By adjusting

the coupling strength, this method can control the chaotic Buck-Boost converter to the period-2, period-4, period-8 orbits

and the period-3, period-6, period-9 orbits, without determining the unstable periodic orbits (UPOs) in advance.
