Abstract
In this paper, the global exponential robust stability analysis problem is considered for a class of uncertain distributed parameter control systems with time-varying delays. The uncertain parameters are generated from modeling errors as well as parameter variations in the systems. The purpose of the problem addressed is to derive some easy-to-test conditions such that the dynamics of the uncertain system is globally exponentially robustly stable. By employing a new Lyapunov-Krasovskii functional, a linear matrix inequality (LMI) approach is developed to establish the desired sufficient conditions and therefore global exponential robust stability for the uncertain distributed parameter control systems with time-varying delays can be easily checked by utilizing the numerically efficient Matlab LMI toolbox. A numerical example is exploited to show the usefulness of the derived LMI-based stability conditions.
