摘要
This paper studies the problem of output feedback stabilization for a class of stochastic nonlinear systems with the unknown output function. For stochastic nonlinear systems, the maximal open sector Δ of output function is given. As long as output function belongs to any closed sector included in Δ, by constructing a reduced-order observer and C~2 Lyapunov function and using the homogeneous domination method, an output feedback controller is constructed to render the closed-loop system globally stable in probability and all states can be regulated to the origin almost surely.
