An alternative formulation of stability criteria for positive systems has been proposed. The results are based on a theorem of alternatives for linear matrix inequality (LMI) feasibility problem, which is a particular case of the duality theory for semidefinite programming problems.}, type={Artykuły / Articles}, title={On the alternative stability criteria for positive systems}, URL={http://www.journals.pan.pl/Content/111587/PDF-MASTER/(55-4)379.pdf}, }
