The feasibility problem for constant scaling in output feedback control is considered. This is an inherently dicult problem [20, 21] since the set of feasible solutions is nonconvex and may be disconnected. Nevertheless, we show that this problem can be reduced to the global maximization of a concave function over a convex set, or alternatively, to the(More)
Recently developed methods of monotonic optimization have been applied successfully for studying a wide class of nonconvex optimization problems, that includes, among others, generalized polynomial programming, generalized mul-tiplicative and fractional programming, discrete programming, optimization over the efficient set, complementarity problems, etc. In(More)
