Abstract: |
The exponential stability of a class of switched systems containing stable and unstable subsystems with impulsive effect is analyzed by using the matrix measure concept and the average dwell- time approach. It is shown that if appropriately a large amount of the average dwell- time and the ratio of the total activation time of the subsystems with negative matrix measure to the total activation time of the subsystems with nonnegative matrix measure is chosen , the exponential stability of a desired degree is guaranteed. Using the proposed switching scheme ,we studied the robust exponential stability for a class of switched systems with impulsive effect and structure perturbations. Simulations validate the main results. |
