NUMERICAL CRITERIA FOR ROBUST CONTROL OF CONTINUOUS SYSTEMS

This article discusses the structural robustness of continuous systems whose model is not well known. Two classes of systems are considered: 1. being two positive data matrices 2. Where f (x) is unknown and generally nonlinear. In both cases, A is a Hurtwitz ’s matrix . A sufficient condition for asymptotic stability is then established for each class as defined. Numerical examples are given to illustrate the results presented and to show improvement compared to past work s.
