Abstract
A sufficient condition for robust stability is presented. Comparing it with the small gain theorem, it incorporates both gain and phase information of the uncertain system and thus reduces the conservativeness of the theorem. The proposed quantitative robust stability criterion is employed to develop a robust PID controller design. Finally, simulations are presented to illustrate the proposed method
