COEFFICIENT DETERMINATION PROGRAM, COEFFICIENT DETERMINATION METHOD AND COEFFICIENT DETERMINATION APPARATUS

摘要

PROBLEM TO BE SOLVED: To reduce a calculation amount required for identification of a system represented by a differential equation.;SOLUTION: The present coefficient determination method includes a process for calculating a first differential coefficient when setting an order of a differential equation representing a system to be a first order based on a result of discrete Fourier transformation of a digital input to the system and a digital output from the system, reading a second differential coefficient from a storage apparatus when setting the order of the differential equation to be a second order, determining convergence of the differential coefficient of the differential equation based on comparison between the first differential coefficient and the read second differential coefficient and determining the differential coefficient of the differential equation based on determination.;SELECTED DRAWING: Figure 4;COPYRIGHT: (C)2018,JPO&INPIT
