Continuously dynamic output feedback control for T-S fuzzy nonlinear networked control systems

Stability and H-infinity optimal control of nonlinear networked control systems (NNCSs) with distributed delays and disturbance are studied in this paper. We develop a hybrid Takagi-Sugeno fuzzy model for nonlinear plant interconnected with continuously dynamic output feedback controller. Sufficient conditions are derived by constructing Lyapunov-krasovskii functional, which insure that the system is asymptotically stable and could achieve γ - suboptimal H-infinity stabilization. Approach to obtaining disturbance attenuation level and parameters of sub-/optimal controller is given in the form of linear matrix inequalities.
