Generalized S‐procedure and finite frequency KYP lemma
Tetsuya Iwasaki, Gjerrit Meinsma, Minyue Fu · Mathematical Problems in Engineering · 2000
The contribution of this paper is twofold. First we give a generalization of the S‐procedure which has been proven useful for robustness analysis of control systems. We then apply the generalized S‐procedure to derive an extension of the Kalman – Yakubovich – Popov lemma that converts a frequency domain condition within a finite interval to a linear matrix inequality condition suitable for numerical computations.
