Abstract: |
The dynamic behavior of commensal symbiosis system with both feedback control and Allee effect is complex. In this paper,the influence of additive Allee effect on the dynamical behavior of the system has been studied based on the feedback control commensal symbiosis system. It is proved that the conditions for the existence of positive equilibrium point are sufficient to ensure the global attractive of the system. By constructing an appropriate Lyapunov function,the sufficient conditions for the global stability of the equilibrium point are obtained. The research shows that Allee effect does not affect the stability of the equilibrium point of the feedback control biased commensal symbiosis system,but affects the position of the equilibrium point. |
