For the problem of H_∞ tracking control for a class of networked control systems(NCSs) based on the T-S model, by using input-delay and parallel distributed compensation(PDC) techniques, a state tracking error model based on the TS model is firstly established in which both network-induced delay and data packet dropout are considered. Furthermore, with the Lyapunov stability theory and the improved free weighting matrix method, several criteria ensuring the prescribed H_∞ tracking performance can be derived. Simultaneously, the non-fragile fuzzy controller design method is also presented. Finally, a numerical example is given to demonstrate the effectiveness of the proposed scheme.
