Description
Summary:The method of resonant parametric perturbation is a simple non-feedback chaos control method which is easy to implement in practice. In this paper, an optimal strategy is applied to stabilize an unstable orbit in a chaotically operating current-mode controlled buck-boost converter. Optimal values of initial phase angles are computed corresponding to minimum perturbation amplitudes. With this optimal perturbation, the converter operating in a chaotic regime can be controlled to operate in an unstable period-1 orbit that exists in the original chaotic attractor.
