FIELD: information technology.
SUBSTANCE: invention relates to engineering and computer science, and more specifically, to a method for predicting the state of a technical system based on difference functions. A method for predicting the state of a technical system based on difference functions is provided, in which data on the operation of the system are accumulated, based on which a method of constructing a model is selected, obtaining approximation of indicators in their discrete digital representation, obtaining current performance indicators, obtained current values are compared with the values of difference equations and difference equations of the following order are obtained, the state of the system is predicted and solutions, indicators and states are used as control actions.
EFFECT: possibility of using differences of not only the first but also higher orders, which makes it possible to effectively predict the state of a system is achieved.
