Guaranteed cost control for uncertain fuzzy time-delay systems with sampled-data input

The guaranteed cost control for uncertain Takagi-Sugeno (T-S) fuzzy time-delay systems with sampled-data input is considered in this paper. In order to treat the sampled-data input problem, the time-varying delay transformation technique and LMI optimization approach are provided to find the upper bound of sampled time and solve the minimization of guaranteed cost.
