An \(H^{\infty}\)-type theory is developed for linear stochastic systems with random state and input matrices which are subjected to stochastic disturbances and controlled by dynamic output feedback. A bounded real lemma is derived to apply a linear matrix inequality approach to the problem. Conditions for existence of a stabilizing controller reducing the norm of the perturbation operator to a level below a given threshold are derived. This generalizes the known results in the non-stochastic case.
