In this paper, we derive some sufficient conditions for practical uniform exponential stability of time-varying perturbed systems based on Lyapunov techniques, whose dynamics are in general unbounded time, the sense that solutions stable and converge to a small neighbourhood origin. Under quite assumptions, first present new converse theorem large class systems, which will be used prove certain properties nonlinear with perturbation. Therefore, function is presented guarantees systems....
The present paper is mainly aimed at introducing a novel notion of stability nonlinear time-delay systems called Rational Stability. According to the Lyapunov-type, various sufficient conditions for rational are reached. Under delay dependent conditions, we suggest observer estimate system states, state feedback controller and observer-based provided. Moreover, global using output given. Finally, study presents simulation findings show feasibility suggested strategy.
In this paper, we present a practical exponential stability result for impulsive dynamic systems depending on parameter. Stability theorem and converse are established by employing the second Lyapunov method. These theorems used to analyze of solution perturbed cascaded systems, Copyright © 2015 John Wiley & Sons, Ltd.
The Lyapunov's second method is one of the most famous techniques for studying stability properties dynamic systems.This technique uses an auxiliary function, called Lyapunov which checks a specific system without need to generate solutions.An important question about reversibility or converse method; i. e., given property does there exist appropriate function?The main result this paper Theorem practical asymptotic stable impulsive systems.Applying our Theorem, several criteria on solution...

In this paper, a recurrent neural network with mixed delays which plays an important role is considered. We are concerned the existence, uniqueness and global exponential stability of doubly measure pseudo almost automorphic solutions.

Second, by employing fixed-point theorem some properties functions, sufficient conditions for solutions have been established. Our obtained in paper new....
