Abstract :
This paper is concerned with the robust Hinfin controller design of nonlinear networked control systems (NCSs). A Takagi-Sugeno (T-S) fuzzy model with parametrical uncertainties is used to approximate the NCS in which network-induced delay is time-vary and less than one sample period. In terms of the given model, a fuzzy controller design method is proposed based on Lyapunov approach and linear matrix inequality (LMI). A feedback gain of a memoryless controller can be obtained by solving a set of LMIs. An example is given to show the effectiveness of the proposed method
