Improved Quadratic Convex Technique to Stability Analysis of Continuous-Time Delayed Systems

An improved quadratic convex technique is proposed. From which, asymptotic stability criteria for a class of continuous-time delayed systems are established. A numerical example is presented to illustrate the availability of theoretical results. The main contributions of this paper are summarized as follows: (i) The improved quadratic convex technique is a generalization of the existing results; and (ii) less conservative asymptotic stability criteria for continuous-time delayed systems are derived.
