| Abstract: | For a class of high-order stochastic nonlinear systems,the problem of output-feedback stabilization is investigated.By adopting an effective observer and choosing the appropriate Lyapunov function,an output-feedback controller is constructed to ensure that the equilibrium at the origin of the closed-loop system is globally asymptotically stable in probability,and the output can be regulated to the origin almost surely.A simulation example shows the effectiveness of the output-feedback controller. |
