A sufficient condition for stability of a polytope of matrices
نویسنده
چکیده
In this paper, we study the stability of interval dynamical systems. A sufficient condition for the stability of a polytope of matrices, which is shown to be necessary and sufficient for a certain class of matrices, is obtained. The results developed can also be applied to the stability of a positive cone of matrices and sufficient conditions for the stability of interval dynamical systems are obtained. A relationship between real parts of eigenvalues and matrix measures is also presented.

Preliminary results on the stability of switched positive linear systems
It was recently conjectured that the Hurwitz stability of a polytope of Metzler matrices is a necessary and sufficient condition for the stability of the associated switched linear system for arbitrary switching sequences. In this paper we show: (i) that this conjecture is true for a polytope constructed from a pair of second order Metzler matrices; (ii) that the conjecture is true for general ...
متن کاملA note on positive deniteness and stability of interval matrices
It is proved that by using bounds of eigenvalues of an interval matrix, someconditions for checking positive deniteness and stability of interval matricescan be presented. These conditions have been proved previously with variousmethods and now we provide some new proofs for them with a unity method.Furthermore we introduce a new necessary and sucient condition for checkingstability of interval...
متن کاملA Mathematical Analysis of Critical Condition for Energy based Lyapunov Function for Polytope of Matrices
−Critical condition is derived for parameter−dependent quadratic Lyapunov function for a polytope of matrices. Condition gives some critical points for the plant, such that it becomes impossible to get parameters of Lyapunov function. In this paper first design is proposed of the memory less feedback controller for uncertain dynamic system with time varying delay. It is assumed that uncertainti...
متن کاملA Less Conservative LMI Condition for Robust D -Stability of Polynomial Matrix Polytopes - A Projection Approach
This technical note investigates the problem of checking robust -stability of a polytope of polynomial matrices. Finsler’s projection lemma is taken to derive a new sufficient condition in terms of a linear matrix inequality (LMI) feasibility problem. The basic idea behind this condition is to lift the existing stability condition into the one of larger space by means of Finsler’s lemma and, ba...
