The value of integral quadratic performance index of quality is equal to the value of Lyapunov functional for the initial function of the time-delay system. The Lyapunov functional is determined by means of the Lyapunov matrix}, title={Lyapunov matrices approach to the parametric optimization of time-delay systems}, URL={http://www.czasopisma.pan.pl/Content/84378/PDF/1.pdf}, doi={10.1515/acsc-2015-0018}, }
