The paper is concerned with non-fagile control design via static output feedback controller for fuzzy stochastic systems that are subject to stochastic disturbances. Many theoretical control design methods given in the literature do not take case of any disturbance into the system and variations in control gains, and they assume all the states of the system are available for the feedback control. In the practical situations, however, unexpected disturbances come into the system and malfunction may occur in actuators. Hence, a non-fragile output feedback control design is desired. In this paper, robust stabilization via static output feedback control with uncertain control gain for fuzzy stochastic systems is considered and a control design of robust stabilizing controllers is proposed. The stability analysis of the closed-loop system and controller design via descriptor system approach are given in terms of LMI conditions, which are less conservative than the existing results. An illustrative example is provided to show the effectiveness of the proposed method.
