Abstract:
An augmented system model may include a system high fidelity model that generates a first output. The augmented system model may further include a data driven model to receive data associated with the first output and to generate a second output, and a feature space version of the second output may be output from the augmented system model. Monitoring nodes may each generate a series of current monitoring node values over time representing current operation of an industrial asset. A model adaptation element may receive the current monitoring node values, calculate a feature space version of current operation, and compare the feature space version of the second output of the augmented system model with the feature space version of current operation. Parameters of the data driven model may then be adapted based on a result of the comparison.
