The H-infinity tracking control problem is studied for a class of nonlinear networked control systems(NCSs).In NCSs,a Takagi-Sugeno fuzzy model is adopted to describe the nonlinear controlled plant,and the tracked plant is rep-resented by a linear stable reference model.By using input-delay and parallel distributed compensation(PDC) techniques,we build a novel state tracking error model based on the system states at the updating instant of a zero-order holder in which both network-induced delay and data pac...
