P. Florchinger, FEEDBACK STABILIZATION OF AFFINE IN THE CONTROL STOCHASTIC DIFFERENTIAL-SYSTEMS BY THE CONTROL LYAPUNOV FUNCTION-METHOD, SIAM journal on control and optimization, 35(2), 1997, pp. 500-511
The purpose of this paper is to study the asymptotic stability in prob
ability of affine in the control stochastic differential systems. Suff
icient conditions for the existence of control Lyapunov functions lead
ing to the existence of stabilizing feedback laws which are smooth, ex
cept possibly at the equilibrium point of the system, are provided.
