Abstract

Augmented Lyapunov functional was utilized to found a few improved stability criteria. It was easy to calculate the upper bounds on the delays as well as the free-weighting matrices through linear matrix inequalities. The results show that the novel strategy is less conservative than previous ones for solving the problem of delay-dependent robust stability of neutral systems. And two numerical examples are given to demonstrate significant improvements over some existing results.
