Abstract
Robust stability of the state-predictive and the Smith control systems for plants with a pure delay is studied. First, the Nyquist-type stab ility condition is derived for robust stability. Then, the condition i s transformed and a robust stability criterion is given in terms of th e Nyquist plots of the complementary sensitivity function and the erro r function. Based on this criterion, we present a method to obtain gra phically stability margins in the delay-time and the gain. (C) 1998 Jo hn Wiley & Sons, Ltd.
