Abstract: |
The aim of this paper is to study the practical $\phi_{0}$-stability in probability (P$\phi_{0}$SiP) and practical $\phi_{0}$-stability in pth mean (P$\phi_{0}$SpM) of switched stochastic nonlinear systems. Sufficient conditions on such practical properties are obtained by using the comparison principle and the cone-valued Lyapunov function methods. Also, based on an extended comparison principle, a perturbation theory of switched stochastic systems is given. |
