Позорная война рф против Украины

Начата 20 февраля 2014 и полномасштабно продолжена 24 февраля 2022 года. С первых же минут рф ведет ее с нарушением законов и правил войны, захватывает атомные станции, уничтожает бомбардировками мирное население и объекты критической инфраструктуры. Правители и армия рф - военные преступники. Все, кто платит им налоги или оказывают какую-либо поддержку - пособники терроризма. Народ Украины вас никогда не простит и ничего не забудет.

The paper deals with the approaches to development of open-loop systems of welding current stabilization in resistance spot welding machines at mains voltage fluctuations. A microcontroller regulator of resistance welding is described, which provides automatic determination of the initial angle between full-phase current and voltage of the machine, as well as welding current stabilization at mains voltage fluctuations. System of angle determination and current stabilization is implemented as finite state machine with digital model of the object of control, presented in the tabulated form. This enabled application of a simple general purpose eight-bit microcontroller for the regulator. 7 Ref., 1 Figure.
