Numerical checking method for positive invariance of polyhedral sets for linear dynamical systems [PDF]
Bulletin of the Polish Academy of Sciences: Technical Sciences, 2020 Positively invariant sets play an important role in the theory and applications of dynamical systems. The stability in the sense of Lyapunov of the equilibrium x = 0 is equivalent to the existence of the ellipsoidal positively invariant sets.

A Matching-Strategy-Inspired Preconditioning for Elliptic Optimal Control Problems
Mathematics, 2023 In this paper, a new preconditioning method is proposed for the linear system arising from the elliptic optimal control problem. It is based on row permutations of the linear system and approximations of the corresponding Schur complement inspired by the

A Matrix Approach for Analyzing Signal Flow Graph
Information, 2020 Mason’s gain formula can grow factorially because of growth in the enumeration of paths in a directed graph. Each of the (n − 2)! permutation of the intermediate vertices includes a path between input and output nodes.

A method for constructing an optimal control strategy in a linear terminal problem
Журнал Белорусского государственного университета: Математика, информатика, 2021 This paper deals with an optimal control problem for a linear discrete system subject to unknown bounded disturbances, where the control goal is to steer the system with guarantees into a given terminal set while minimising the terminal cost function. We
