Fourier Series in Control Theoryor asymptotic approximations of the functions which may be written by the relations of type ., ~, and we estimate their growth (when the argument tends to infinity) by means of real numbers. Simple estimates were regarded in subsection 3.2.1.custody 发表于 2025-3-24 07:28:58

General Asymptotic Properties of Linear Differential Equations, are functions specified on an interval ]., .[, where ., . are points of the real axis (one or both of the points . and . can be infinitely large, . = 1, 2, ..., .). First, the equation is reduced to an equivalent (in some sense) system written in the form . where . = (.., .., ..., ..)., ., and .(.) = (.. (.)). a square matrix specified on ]., .[.tinnitus 发表于 2025-3-25 02:35:52
