Vertex criteria for the robust stability of interval systems
Weijie Mao · Journal of Zhejiang University(Engineering Science) · 2000
Based on a nonlinear power transformation,the robust stability problem of interval matrices has been transformed into a nonsigularity problem of a family of paramaterized matrices and then via the algorithm of robust diagonal dominance,some sufficient conditions for the robust stability of the system matrices are derived. These conditions are composed of the systems own elements and do not impose any requirements on the elements of the system matrices.
