METHOD FOR MATCHING COMPUTED CURVE TO TARGET CURVE FOR THE SAKE OF PARAMETER IDENTIFICATION

摘要

PROBLEM TO BE SOLVED: To provide a method and a system for matching a computed curve to a target curve to enable realistic engineering simulations.

SOLUTION: Optimization of parameter identification is achieved by adjusting the parametric inputs of a simulation model such that the discrepancy between two curves 302 and 304 is minimized. Because points 312 and 316 on the two curves 302 and 304 to be matched are paired, matching of any two open curves, including hysteretic curves, can be handled. Curves that are completely set apart in their original coordinates can be merged to a common coordinate system for parameter identification without the computational instability problems. A partial matching scheme (410g) is used for mapping the point 312 defining a shorter curve of the two curves 302 and 304 to a set of the mapped point 316 on a longer curve. One or more offsets 320 from a first point of the longer curve 304 are used for multiple attempts 401g to find a best fit.
