DELAY-DEPENDENT ROBUST H_2/H_∞ CONTROL FOR TIME-DELAY SYSTEMS WITH POLYTOPIC UNCERTAINTY

摘要

In this paper, new separated delay-dependent H_∞ and H_2 performance criteria are derived for a class of time-delay systems. Then they are extended to design a multiobjective robust H_2/H_∞ controller for polytopic uncertain systems with time delay. All the conditions are given in terms of linear matrix inequalities (LMIs). Numerical examples are given to illustrate the proposed method.
