ROBUST STABILITY-CRITERIA FOR DYNAMICAL-SYSTEMS INCLUDING DELAYED PERTURBATIONS

In this note, we consider the problem of robust stability of uncertain time-delay dynamical systems. A new robust stability criteria for lin ear dynamical systems subject to delayed time-varying and nonlinear pe rturbations is derived. The results obtained in this note are less Con servative than the ones reported so far in the literature. Some analyt ical methods are employed to investigate the bound on the perturbation s so that the systems are stable. A numerical example is given to demo nstrate the utilization of our results.
