Abstract :
We study the frequency response of interval systems using Kharitonov stability theory on FIRST ORDER complex polynomial set. For an interval transfer function set, we show that the minimal real part of the frequency response at any fixed frequency is attained at some prescribed vertex transfer functions. Some extensions and applications in positivity verification and robust absolute stability of feedback control systems are also presented.
