Stability and Hopf Bifurcation in a Prey-Predator System with Disease in the Prey and Two Delays
Abstract and Applied Analysis, 2014 This paper is concerned with a prey-predator system with disease in the prey and two delays. Local stability of the positive equilibrium of the system and existence of local Hopf bifurcation are investigated by choosing different combinations of the two ...

Adaptive mixing formation control of multiquadrotor unmanned aerial vehicle systems
Asian Journal of Control, EarlyView.Abstract This paper presents a distributed adaptive mixing control (AMC) design for formation maintenance of systems of multiquadrotor UAVs (q‐UAVs) during commanded path‐tracking maneuvers. The proposed formation control scheme has a two‐level structure. The high level defines the desired trajectories for rigid and persistent formation acquisition and

Hopf bifurcation of a computer virus spreading model in the network with limited anti-virus ability
Advances in Difference Equations, 2017 A delayed computer virus spreading model in the network with limited anti-virus ability is proposed in the present paper. Local stability and the existence of a Hopf bifurcation are proved by taking the time delay as the bifurcation parameter and ...

Asian Journal of Control, EarlyView.Abstract Large swarms often adopt a hierarchical network structure that incorporates information aggregation. Although this approach offers significant advantages in terms of communication efficiency and computational complexity, it can also lead to degradation due to information constraints.
