D-STABILITY CRITERIA FOR LINEAR UNCERTAIN CONTINUOUS MULTI-DELAYS SYSTEMS

摘要

In this paper, the D-stability testing problem for a class of uncertain continuous multi-time-delay systems is studied. Several criteria for testing that all characteristic roots of the above systems are located inside a specified disk D(α,r)with center at α + j0 and radius r in the left-half complex plane are derived. A numerical example is also illustrated to demonstrate the applicability of our results.
