Singularity Induced Bifurcation and Control in Bio-economic Model

In this paper,a differential-algebraic model system which considers a prey-predator system with stage structure for prey and harvest effort on predator is proposed. By using the differential-algebraic system theory and bifurcation theory, dynamic behavior of the proposed model system is investigated. Local stability analysis of the model system reveals that there is a phenomenon of singularity induced bifurcation due to variation of the economic interest of harvesting, and state feedback controllers are designed to stabilize the proposed model system at the interior equilibrium.Finally, numerical simulations are carried out to show the consistency with theoretical analysis obtained in this paper.
