Guaranteed cost control of T–S fuzzy systems with input delay

This paper is concerned with the problem of guaranteed cost control for Takagi–Sugeno (T–S) fuzzy systems with time-varying input delay. The input delay is of interval type, and no restriction is imposed on the derivative of the time delay. Based on free-weighting matrix method, new delay-dependent sufficient conditions for the existence of a fuzzy guaranteed cost controller are provided by means of linear matrix inequalities. Some examples are used to illustrate the effectiveness of the proposed method. Copyright © 2007 John Wiley & Sons, Ltd.
