| 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. |
