Quadratic stability and quadratic stabilization for singular system families
广义系统族的二次稳定与二次镇定

In this paper, the uncertainty of an uncertain singular system is described in the viewpoint of a system family. The concept of `generalized quadratic stable cone' is proposed. In terms of matrix inequalities, the necessary and sufficient conditions are derived, under which the considered uncertain system is generalized quadratic stable/stabilizable one.
