Description

technical field [0001] The invention relates to a process management and control method for multi-source heterogeneous data fusion and model correction, which belongs to the field of automation technology. Background technique [0002] Land-based platform systems, aerospace systems, complex mechanical systems, and other systems often rely on theoretical modeling, computer simulation modeling, and test sampling analysis to determine the parameters, performance optimization, and rationality of the designed system in the process of design to program determination. verification etc. However, in the modeling of theoretical models and simulation models, some links are often simplified in order to facilitate the solution, resulting in a poor fit between the solution results and the actual response. At the same time, in the process of testing the prototype, there are often inconsistencies in multiple sets of test data due to errors that are difficult to eliminate, and there are cas...
