| Abstract: |
| In this paper, we study the state feedback control problem for a class of highorder stochastic nonlinear systems with time-varying delay. Using the Lyapunov method, a suitable Lyapunov functional is constructed and combined with the stability theory of stochastic systems, we obtain a state feedback controller which can make the global asymptotical stability (GAS) in probability of the closed-loop system. System in this paper has more general high-order terms, which generalizes the previous result of global asymptotic stability in probability of a single highorder term system. The efficiency of the state-feedback controller is demonstrated by a simulation example. |
