Title:
NONLINEAR MODEL MODELING METHOD, DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/062754
Kind Code:
A1
Abstract:
Provided are a nonlinear model modeling method, device and a storage medium. Wherein, the method includes: determining the complete design point data for each target nonlinear basis process of each apparatus; establishing the description formula of the nonlinear basis process using the ratio of the similarity number supported by the similarity criterion to the similarity number based on the design point data, to obtain the general model of the nonlinear basis process; the general model includes variable parameters that change nonlinearly with changes in actual operating condition parameters; constructing the machine learning algorithm between the actual working condition parameters and the variable parameters, and establishing the association relationship between the machine learning algorithm and the general model; the general model of the nonlinear general process of all targets of each apparatus and the associated machine learning algorithm constitute the general model of the apparatus. This method can realize the modeling of the nonlinear model for some models including the nonlinear basis process.
