Este artigo estuda uma nova abordagem para análise de sistemas dinâmicos comutados na perspectiva de bifurcação e otimização multiobjetivo. Como primeiro passo, analisamos um sistema dinâmico chaveado simples baseado em um conversor boost com entrada fotovoltaica. Primeiro, na perspectiva do fenômeno de bifurcação, consideramos conjuntos de bifurcações de duplicação de período no espaço de parâmetros. Segundo, numa perspectiva de otimização multiobjetivo, consideramos um trade-off entre potência máxima de entrada e estabilidade. O trade-off é representado por uma frente de Pareto no espaço objetivo. Realizando experimentos numéricos, a relação entre os conjuntos de bifurcações e a frente de Pareto é investigada.

Abstract: This paper studies a novel approach to analysis of switched dynamical systems in perspective of bifurcation and multiobjective optimization. As a first step, we analyze a simple switched dynamical system based on a boost converter with photovoltaic input. First, in a bifurcation phenomenon perspective, we consider period doubling bifurcation sets in the parameter space. Second, in a multiobjective optimization perspective, we consider a trade-off between maximum input power and stability. The trade-off is represented by a Pareto front in the objective space. Performing numerical experiments, relationship between the bifurcation sets and the Pareto front is investigated.
