Annotatsiya V knige privedena metodika otsenki tochnosti tsifrovogo modelirovaniya ob"ektov, opisyvaemykh sistemami obyknovennykh differentsial'nykh uravne-niy, integriruemykh rasprostranyennymi chislennymi metodami. Otlichiem metodiki yavlyaetsya opredelenie tochnosti vosproizvedeniya model'yu takikh kharakternykh dlya inzhenernoy praktiki parametrov perekhodnogo protsessa, kak chastoty, zatukhaniya, amplitudy i fazy vsekh sostavlyayushchikh protsessa. Privedeny universal'nye kharakteristiki chislennykh metodov, oblegchayushchie vybor metoda, otsenku bystrodeystviya proektiruemoy modeli i koordinatsiyu trebovaniy k ney s tochnost'yu opredeleniya parametrov modeliruemogo ob"ekta Predlozheny modifikatsii chislennykh metodov i algoritmov, povyshayushchie vychislitel'nuyu ustoychivost' i bystrodeystvie modeley, operiruyushchikh t.n. «zhestkimi» sistemami differentsial'nykh uravneniy, opisyvayushchikh modeli-ruemye ob"ekty s shirokim diapazonom sobstvennykh chastot.
