In this paper, a dynamic antiwindup compensator design is proposed which\naugments the main controller and guarantees robust performance in the event of\ninput saturation. This is a two stage process in which first a robust optimal\ncontroller is designed for an uncertain linear system which guarantees the\ninternal stability of the closed loop system and provides robust performance in\nthe absence of input saturation. Then a minimax linear quadratic Gaussian (LQG)\ncompensator is designed to guarantee the performance in certain domain of\nattraction, in the presence of input saturation. This antiwindup augmentation\nonly comes into action when plant is subject to input saturation. In order to\nillustrate the effectiveness of this approach, the proposed method is applied\nto a tracking control problem for an air-breathing hypersonic flight vehicle\n(AHFV).\n
