Title:

SYSTEM IDENTIFICATION METHOD, SYSTEM IDENTIFICATION DEVICE, AND PROGRAM

Document Type and Number:

WIPO Patent Application WO/2020/255504

Kind Code:

A1

Abstract:

This system identification method comprises: a step (S1) for measuring frequency responses (ω, HR1), (ω, HR2)…, and (ω, HRn) in a real system under n sets of disturbances of different magnitudes; a step (S3) for calculating frequency responses (ω, HM1), (ω, HM2)…, (ω, HMn) from input to output in n sets of mechanical models M1 to Mn including i sets (i is an integer of 1 or greater) of common parameters that do not change due to disturbance and j sets of disturbance variable parameters that do change due to disturbance; a step (S4) for calculating the values of a total of n sets of evaluation functions F (HRk, HMk) and the sum σF thereof; and steps (S3 to S6) for searching for the values of i sets of common parameters and j × n sets of disturbance variable parameters for which the sum σF would meet convergence conditions.
