This paper investigates the fuzzy tracking control problem for a class of uncertain nonlinear networked control systems (NCSs), which can be represented by a T-S fuzzy modelwith external disturbances. In transmission both networkinduced delay and packet dropout are considered. The controlscheme is based on the parallel distributed compensation (PDC) structure, a fuzzy observer and H∞ performance to attenuate the external disturbances; the stability of the whole closed-loopmodel is provided using a general Lyapunov–Krasovskii functional. The key point of the proposed approaches is toachieve conditions under a linear matrix inequalities (LMI) formulation. Finally, numerical examples and simulation resultsare given to illustrate the effectiveness of the method.
