Robust H_∞ control for uncertain T-S fuzzy time-delay systems with sampled-data input and nonlinear perturbations

摘要

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