Abstract

This paper investigates the problem of designing a robust H∞ state feedback plus state-derivative feedback control mechanism for a class of uncertain nonlinear time-varying delay systems described by a Takagi–Sugeno fuzzy model. A linear matrix inequality approach is applied to derive a robust controller for such a system. The proposed controller satisfies design requirements that ensure that the closed-loop system is asymptotically stable and meets pre-prescribed H∞ performance index values. Finally, the illustrative examples are simulated to illustrate the effectiveness of the proposed methodology. © 2018, The Natural Computing Applications Forum.
