In Chap. 1, we have introduced the basic concepts of fuzzy sets, fuzzy logic, and fuzzy inference mechanism. This chapter aims to present a necessarily selective review on T–S fuzzy systems including their architectures, important properties, and applicability in the field of nonlinear system ...
The division of fuzzy space is very important in the identification of premise parameters, and the Gaussian membership function is applied to the premise fuzzy set. However, the two parameters of Gaussian membership function, center and width, are not easy to be determined. In this paper, based...
In this paper, the H∞ control problem for a class of T–S fuzzy time-delay nonlinear system with sampled-data input has been studied. Based on the LMI optimization approach and time-varying delay transformation technique, a delay-dependent criterion has been proposed to guarantee the upper bou...
This study is concerned with the problem of robust H∞-tracking control design for T–S fuzzy systems with partly immeasurable premise variables and external disturbances. A novel fuzzy observer is constructed by using the measurable premise variables and the estimations of immeasurable premise variables...
