【摘要】：正This paper considers a concrete stochastic nonlinear systems with stochastic unmeasurable inverse dynamic.Motivated by the concept of integral input-to-state stability(ilSS) in deterministic systems and stochastic input-to-state stability (SISS) in stochastic systems,a concept of stochastic integral input-to-state stability(SiISS) using Lyapunov function is introduced. A constructive strategy is proposed to design a dynamic output-feedback control law,which drives the state to the origin almost surely while keeping all other closed-loop signals almost surely bounded.At last,a simulation is given to verify the effectiveness of the control law.
