Abstract A swarming model is a that describes the behavior of social aggregation large group animals or community humans. In this work, includes short-range repulsion and long-range attraction with presence time delay investigated. Moreover, convergence to consensus representing dispersion cohesion properties proved by using Lyapunov functional approach. Finally, numerical results are provided ...

In this paper we study the exponential and uniform exponential stability problem for linear discrete time-varying systems with independent stochastic perturbations. We give two representations of the solutions of the discussed systems and we use them to obtain necessary and sufficient conditions for the two types of stability. A deterministic characterization of the uniform exponential stabilit...

The paper is concerned with robust stability criteria for Takagi- Sugeno (T-S) fuzzy systems with distributed delays and time delay in the leakage term. By exploiting a model transformation, the system is converted to one of the neutral delay system. Global robust stability result is proposed by a new Lyapunov-Krasovskii functional which takes into account the range of delay and by making use o...
