Abstract :
Addresses the design of linear-quadratic-Gaussian (LQG) controllers for uncertain linear time-invariant systems that are either norm-bounded or belong to a given sector. The system matrices are assumed to be affine functions of parameters confined to a convex polytopic region in the parameter space. The resulting controllers themselves satisfy certain norm or sector conditions and provide robust stability as well as optimal performance
