Generalized KYP lemma: unified frequency domain inequalities with design applications
Tetsuya Iwasaki,Shinji Hara +1 more
TL;DR: A necessary and sufficient condition for an S-procedure to be lossless is developed, and the result is used to generalize the KYP lemma in two aspects-the frequency range and the class of systems-and to unify various existing versions by a single theorem.
