| Abstract: | Based on stability criteria of discrete singular systems by using Lyapunov method and piecewise fuzzy Lyapunov function,the stability is studied for discrete singular fuzzy systems with their inputs employing two-overlapped fuzzy partition.A new sufficient condition that searches for a common positive-definite symmetric matrices in each maximal overlapped-rule group is obtained to check the stability of the discrete singular T-S fuzzy systems.An example shows the stability result. |
