DARE solutions for LQ optimal and suboptimal control of systems with multiple input–output delays

P Ignaciuk - Journal of The Franklin Institute, 2016 - Elsevier
The central issue in linear-quadratic (LQ) optimal control problems is finding a solution to
Riccati equation. In this paper, infinite-horizon LQ problem and the associated discrete-time …

Traffic control under scarce resources in wireless networks-a game-based approach

M Morawski, P Ignaciuk - 2015 19th International Conference …, 2015 - ieeexplore.ieee.org
Typically, in order to organize the traffic in networks, some routing protocol is involved to
