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.<>
