Output Feedback Stabilization Of A Class Of Stochastic Nonlinear Systems

In this paper, an output feedback stabilization is considered for a class of stochastic nonlin-ear systems, whose nonlinear terms admit an incremental rate depending only on the measured output. First, a high-gain observer is designed with a gain coming from a Riccatti equation. Sec-ond, by the backstepping approach, an output feedback controller is obtained, which guarantees global stability in probability and regulation of the state of the plant to zero.
