摘要：

In this note, a necessary and sufficient condition for robustly stabilizing a family of plants described by perturbations of fixed coprime factors of a plant is given. The computation of the largest stability margin is discussed via solving a nonsquare l1 optimal control problem. A new algorithm for obtaining lower approximations of the minimum value of the optimization problem mu(0) is proposed. This, together with the standard algorithm which provides upper approximations, mu(0) can be computed within any degree of accuracy.
