METHOD FOR DETERMINING AN ANOMALY IN A CYBER-PHYSICAL SYSTEM Russian patent published in 2023 - IPC G06F21/50 

FIELD: industrial safety.

SUBSTANCE: invention relates to the field of industrial safety, and more specifically to methods for determining anomalies in a cyber-physical system. According to the implementation variant, a computer-implemented method for determining an anomaly in a cyber-physical system (CPS) is used, in which: at least one diagnostic rule is formed, designed to calculate at least one auxiliary parameter of the CPS, by specifying: a set of parameters of the CPS used in the diagnostic rule; a method for calculating the values of at least one auxiliary parameter of the CPS according to the values of a set of parameters of the CPS; at least one input window/time interval for the values of a set of parameters of the CPS, as well as an output window/time interval for calculating the values of the auxiliary parameter of the CPS; calculating the values of at least one auxiliary parameter of the CPS for the output window, using the values of the set of parameters of the CPS for the input window in accordance with the formed diagnostic rule; determining the anomaly in the CPS based on the values of all parameters of the CPS.

EFFECT: increase in the accuracy of detecting anomalies in the CPS.
