Stochastic input-to-state stability and applications to global feedback stabilization. (English) Zbl 0953.93073

The author considers the stochastic composite system described by the following stochastic differential Ito equations

Σ 1 :dx=f 1 (x,u)dt+g 1 (x,u)dw(t)
Σ 2 :dy=f 2 (x,y,u)dt+g 2 (x,y,u)dw(t)

where (x,y) n × k are the vectors of state, u m is the control (input) vector, f i ,g i ,i=1,2 are nonlinear vector functions of appropriate dimensions and w is a standard Wiener process.

The author introduces new definitions of stochastic γ-input to state stability and derives sufficient conditions for global stabilization in two cases, i.e., by means of output (linear and bounded) static feedback and by a dynamic feedback controller.
