Abstract :
To transform the Buck-Boost converter from 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.
