Gn. Milshtein et Lb. Ryashko, STABILITY AND STABILIZATION OF AUTONOMOUS SYSTEM ORBITS UNDER STOCHASTIC PERTURBATIONS, Journal of applied mathematics and mechanics, 56(6), 1992, pp. 855-862
Both the necessary and sufficient conditions for exponential orbital s
tability in the mean square for periodic motions of stochastic systems
are obtained, using the method of orbital Lyapunov functions. From th
e sufficiency criteria an orbit stabilization method is given.
