Robust stability of uncertain T–S fuzzy time-varying systems

In this paper, the global exponential stability for a class of uncertain Takagi–Sugeno (T–S) fuzzy time-varying systems is investigated. Based on the comparison theorem, a simple criterion is derived to guarantee the global exponential stability of such systems. An estimate of the exponential decay rate of such stable systems is also presented. Finally, a numerical example is provided to illustrate the use of the main result.
