FIELD: automatic control equipment. SUBSTANCE: ultra-fast regulation is defined as response to deviation with error depending only on delay of controlled object, when increased response action results in pulsation, and decreased response action results in increased error. This regulation provides complete stability range. However, short time deviations, which duration is less than double delay of controlled object are doubled by amplitude in course of such regulation. This resonance is attenuated by decreased response action, but this decreases response speed and increases regulation error. Invention provides method for elimination of resonance without increase in regulation error due to narrowing short-time response action by double object delay, holding its increase for one object delay and preventing delay of its decreasing. This results in possibility to eliminate redundant response action, as cause of resonance because all regulation error is shifted into under-response action without increase of its amplitude. Elimination of over-response action provides also possibility to keep required parameter in proximity to maximal tolerance limit. EFFECT: elimination of resonance without speed tradeoff. 3 dwg
