Способ оценки и предсказания состояния технической системы путем анализа дискретных производных показателей ее функционирования, предусматривающий следующие стадии:A method for assessing and predicting the state of a technical system by analyzing discrete derivatives of indicators of its functioning, which includes the following stages: 1) накапливают данные о функционировании технической системы, в виде цифровых показателей параметров ее функционирования, связанных с моментами времени;1) accumulate data on the functioning of the technical system, in the form of digital indicators of the parameters of its functioning, associated with points in time; 2) на основе накопленных показателей вычисляют дискретные производные в виде отношения изменения показателя за некоторый интервал времени к величине этого интервала;2) on the basis of the accumulated indicators, discrete derivatives are calculated in the form of the ratio of the change in the indicator for a certain time interval to the value of this interval; 3) на основе вычисленных дискретных производных определяют экстремумы показателей функционирования по признаку перемены знака производной, а также независимо от этого вычисляют скорость изменения показателей;3) on the basis of the calculated discrete derivatives, the extrema of the performance indicators are determined by the sign of the derivative's sign reversal, and also independently of this, the rate of change of the indicators is calculated; 4) на основе выборки из произвольного набора полученных экстремумов показателей функционирования и/или скорости изменения показателей с учетом периодичности их наступления описывают состояния технической системы в будущие моменты времени, оценивая ее состояние и предсказывая его;4) on the basis of a sample from an arbitrary set of the obtained extrema of the performance indicators and / or the rate of change of indicators, taking into account the frequency of their occurrence, describe the state of the technical system at future moments in time, assessing its state and predicting it; 5) полученные на стадиях 3 и/или 4 результаты сохраняют и используют в качестве предсказывающих событий или управляющих воздействий, позволяющих достичь безопасного и оптимального функционирования технической системы.5) the results obtained at stages 3 and / or 4 are stored and used as predictive events or control actions that allow achieving safe and optimal functioning of the technical system.
