A new robust stability analysis of uncertain switching fuzzy time-delay systems

In this work, delay-independent stability conditions for discrete-time switched fuzzy TS time-delay systems described by delayed difference equations are presented. Vectorial norm approach and M-matrix properties are utilized for the stability analysis. The main benefit of this technique is that it avoids the problem of existence of Lyapunov functions. A numerical example is given to demonstrate the efficiency of the proposed method.
