Abstract
Обґрунтовано методологічні підходи до удосконалення системи керування механізму вертикального
наведення пакету напрямних реактивної системи залпового вогню БМ-21 у напрямі підвищення швидкодії та точності позиціювання. Обґрунтовано
використання триконтурної позиційної структури
системи керування механізмом наведення з контуром
регулювання положення та нечітким коректором.
Отримано математичну модель руху пакету напрямних та розраховано їх реакцію. Експериментально
отримано параметри елементів системи наведення, їхні перехідні характеристики та передавальні функції.
The methodological approaches to the improvement of the control system of the vertical guidance mechanism of FM-21 multiple launch missile system to increasing its speed and positioning accuracy are confirmed. The use of the three-circuit positional structure of the control system of the guidance mechanism with a position control loop and a fuzzy corrector is justified. A mathematical model of the guiding package motion has been obtained and its reaction has been calculated. The parameters of the electrical and mechanical elements of a guidance system and their transient characteristics are experimentally obtained. With the use of the approximation procedure, the analytical dependencies of these transient characteristics and corresponding transient functions of various orders of the elements of an electric drive power circuit are obtained.
