In this paper we show that uniformly global asymptotic stability for a family of ordinary differential equations is equivalent to uniformly global exponential stability under a suitable nonlinear change of variables. The same is shown for input-to-state stability and input-to-state exponential stability, and for input-to-state exponential stability and a nonlinear H∞ estimate.
⎯The problem of the global exponential stability of a class of Hopfield neural networks is considered. Based on nonnegative matrix theory, a sufficient condition for the existence, uniqueness and global exponential stability of the equilibrium point is presented. And the upper bound for the degree of exponential stability is given. Moreover, a simulation is given to show the effectiveness of th...
We give characterizations for uniform exponential stability and uniform exponential instability of linear skew-product flows in terms of Banach sequence spaces and Banach function spaces, respectively. We present a unified approach for uniform exponential stability and uniform exponential instability of linear skew-product flows, extending some stability theorems due to Neerven, Datko, Zabczyk ...
We study the relationship between global exponential stability of an invariant manifold and existence a positive semidefinite Riemannian metric which is contracted by flow. In particular, we investigate how following properties are related to each other (in case): 1) A globally “transversally” exponentially stable; 2) corresponding variational system admits same property; 3) there exists degene...
We study the a.s. exponential stability of the optimal lter w.r.t. its initial conditions. A bound is provided on the exponential rate (equivalently, on the memory length of the lter) for a general setting both in discrete and in continuous time, in terms of Birkhoo's contraction coeecient. Criteria for exponential stability and explicit bounds on the rate are given in the speciic cases of a di...
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...
