Abstract

In the paper a Lyapunov matrices approach to the parametric optimization problem of time-delay systems with a P-controller is presented. 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

Abstract

Charity, the core of the Gospel ethos, became one of the founding ideas of European civilization and distinguished it from others. In Polish territories, as in other Western European countries, charity work was conducted primarily by the Church, which together with its sense of Gospel duty, defended the weak by concerning itself with economic development. For this purpose, charitable credit institutions, so-called mounts of piety (montes pietatis), were established. They were continued by reformers, in a somewhat changed form, until the decline of the Polish Commonwealth (Republic). The most original institution of this kind was Rev. Stanisław Staszic’s foundation: the Hrubieszów Agricultural Society, which survived until the days of the Polish People’s Republic.

17. Lyapunov functional for a linear system with both lumped and distributed delay.

Author

Subjects
LYAPUNOV functions, LINEAR systems, TIME delay systems, MATRIX analytic methods, PARAMETER estimation, DISTRIBUTED parameter systems
Abstract

The paper presents a method of determining the Lyapunov quadratic functional for linear time-invariant system with both lumped and distributed delay. The Lyapunov functional is constructed for its given time derivative, which is calculated on the trajectory of the system with both lumped and distributed delay. The method presented gives analytical formulas for the coefficients of the Lyapunov functional. [ABSTRACT FROM AUTHOR]
