SYSTEM AND METHOD FOR DETECTING ANOMALIES IN A CYBER-PHYSICAL SYSTEM Russian patent published in 2023 - IPC G06F21/00 

FIELD: cyber-physical systems.

SUBSTANCE: invention relates to a method and system for detecting anomalies in a cyber-physical system (CPS). In method a) the values of the CPS parameters are collected; b) at least two subsets of CPS parameters are formed from among the CPS parameters; c) at least two anomaly detectors are selected from the list of detectors and at least one generated subset of CPS parameters for each selected detector; d) each subset of CPS parameters is preprocessed before being passed to the corresponding detector, whereas each selected detector has its own set of preprocessing steps; e) at least one anomaly is detected by each selected detector in the data of the subset of CPS parameters corresponding to the detector; f) the combined anomaly in the FSC is identified by aggregating the results obtained from the selected detectors.

EFFECT: increasing the accuracy of detecting anomalies in the CPS by using a plurality of detectors of anomalies in the CPS followed by combining the results of all these detectors.
