Abstract

It is pointed out in this paper that the criticism raised by Doyle and Stein (1981) against the inverse nyquist array (INA) design method was not tenable. Actually, the robustness behaviour of a diagonally dominant control system depends on its degree of diagonal dominance. Based upon a large amount of numerical calculation, this paper gives the least degree of diagonal dominance required to keep a system robustly stable under the perturbation of given intensity. On this basis an improved design method is proposed-the robust INA method (RINA). An example is given.<>
