Neste trabalho se estuda a análise de estabilidade Qr e se calcula o domínio de atração de uma classe particular de sistemas híbridos conhecida como sistemas chaveados. No conceito de estabilidade Qr, usa-se uma função de Lyapunov dependente dos estados de tipo polinomial e diferente da quadrática convencional. O problema a resolver é apresentado como um problema de otimização convexa em termos de inequações matriciais lineares (LMIs). Resultados numéricos são apresentados exibindo uma abordagem menos conservadora que a quadrática convencional e a abordagem biquadrática ([5]), no cálculo das respectivas regiões de estabilidade para um dado exemplo.References
