BOOTSTRAP DATA METHODOLOGY FOR SEQUENTIAL HYBRID MODEL BUILDING

摘要

A method for modeling engine operation includes the stepsof: 1. collecting a first plurality of sensory data, 2.partitioning a flight envelope into a plurality ofsub-regions, 3. assigning the first plurality of sensory datainto the plurality of sub-regions, 4. generating an empiricalmodel of at least one of the plurality of sub-regions, 5.generating a statistical summary model for at least one of theplurality of sub-regions, 6. collecting an additionalplurality of sensory data, 7. partitioning the secondplurality of sensory data into the plurality of sub-regions,8. generating a plurality of pseudo-data using the empiricalmodel, and 9. concatenating the plurality of pseudo-data andthe additional plurality of sensory data to generate anupdated empirical model and an updated statistical summarymodel for at least one of the plurality of sub-regions.
