Abstract :
This paper considers the robust stability problem of time-delay systems with block-diagonal uncertainty. A new stability criterion is derived using the refined discretized Lyapunov functional method. The criterion is written in the form of a linear matrix inequality. Numerical examples show the new criterion significantly improve the estimate of the stability limit over some existing results in the literature
