Item Edge theorem for multivariable systems(2002-10) Wang, Long; Wang, Zhizhen; Yu, WenshengThis paper studies robustness of multivariable systems with parametric uncertainties, and establishes a multivariable version of Edge Theorem. An illustrative example is presented.Item Improved results on robust stability of multivariable interval control systems(2002-10) Wang, Zhizhen; Wang, Long; Yu, WenshengFor interval polynomial matrices, we identify the minimal testing set, whose stability can guarantee that of the whole uncertain set. Our results improve the conclusions given by Kamal and Dahleh.Item Stability of polytopic polynomial matrices(2002-02) Wang, Long; Wang, Zhizhen; Yu, WenshengThis paper gives a necessary and sufficient condition for robust D-stability of Polytopic Polynomial Matrices.
