The stability in the sense of Lyapunov of the equilibrium x = 0 is equivalent to the existence of the ellipsoidal positively invariant sets. The constraints on the state and control vectors of dynamical systems can be formulated as polyhedral positively invariant sets in practical engineering problems. Numerical checking method of positive invariance of polyhedral sets is addressed in this paper. The validation of the positively invariant sets can be done by solving LPs which can be easily done numerically. It is illustrated by examples that our checking method is effective. Compared with the now existing algebraic methods, numerical checking method is an attractive method in that it’s easy to be implemented.}, type={Article}, title={Numerical checking method for positive invariance of polyhedral sets for linear dynamical systems}, URL={http://journals.pan.pl/Content/116288/PDF/21_593-599_01490_Bpast.No.68-3_30.06.20_KG_TeX.pdf}, doi={10.24425/bpasts.2020.133110}, keywords={positively invariant set, linear system, polyhedral set, polyhedral cone, linear programming}, }
