Robust stability analysis of uncertain switching fuzzy systems with time-varying delays

This paper considers robust stability analysis of uncertain continuous-time switching fuzzy systems with time-varying delays based on piecewise fuzzy weighting-dependent Lyapunov-Krasovskii functionals (PFLKFs). Average dwell-time approach and PFLKFs methods are utilized for the stability analysis with free fuzzy weighting matrix scheme. The stability results can be obtained by solving a set of linear matrix inequalities (LMIs) that are numerically feasible. A numerical example is given to demonstrate the efficiency of the proposed method.
