Complex dynamics of a Holling type II prey-predator system with state feedback control. (English)
[J] Chaos Solitons Fractals 31, No. 2, 448-461 (2007). ISSN 0960-0779

Summary: The complex dynamics of a Holling type II prey-predator system with impulsive state feedback control is studied in both theoretical and numerical ways. Sufficient conditions for the existence and stability of positive periodic solutions are obtained by using the Poincaré map and the analogue of the Poincaré criterion. A qualitative analysis shows that the positive periodic solution bifurcates from a solution through a fold bifurcation. The bifurcation diagrams, Lyapunov exponents, and phase portraits are illustrated by an example, in which the chaotic solutions appear via a cascade of period-doubling bifurcations. The superiority of the state feedback control strategy is also discussed.
