摘要
This paper is concerned with a unified framework for asymptotic and transient behavior of stochastic systems. In order to explain this problem explicitly, a concept of mean square (gamma,alpha)-stability is first introduced and two stability criteria are derived. By utilizing an auxiliary definition of mean square (gamma,T)-stability, the relations among mean square (gamma,alpha)-stability, mean square (gamma,T)-stability and finite-time stochastic stability are established. Subsequently, two new sufficient conditions for the existence of state and output feedback mean square (gamma,alpha)-stabilization controllers are presented in terms of matrix inequalities. A numerical algorithm is given to obtain the relation between gamma(min) and alpha. Finally, an example is given to illustrate our results. (C) 2017 Elsevier Inc. All rights reserved.
