✦ Synopsis

This paper considers the stability radius problem of control systems with interval plants and "rst-order controllers. The nominal plant P (s) used for the controller design is the centre of the interval plant. Under the condition that a lead controller C(s) stabilizes P (s), the stability radius of the closed-loop system is determined in terms of the eigenvalues of four frequency-independent matrices of the form H\ @G H AG , where both H @G and H AG are Hurwitz-like matrices.

Robust stability of the state-predictive and the Smith control systems for plants with a pure delay is studied. First, the Nyquist-type stability condition is derived for robust stability. Then, the condition is transformed and a robust stability criterion is given in terms of the Nyquist plots of t
