Takagi-Sugeno fuzziness time-delay output feedback control passivity linear matrix inequality
This paper considers the design problem of passive dynamic output feedback control for uncertain Takagi-Sugeno ( T-S ) fuzzy systems with time-varying delays. Via the application of Lyapunov stability theory and the linear matrix inequality techniques,delay-dependent sufficient conditions are given for the passive stability analysis and the existence of the dynamic output feedback controllers. The dynamic output feedback controller designed here guarantees the robust stability and the passivity of the closed-loop system. A numerical example is given to illustrate the effectiveness of the design approach here.
