APPARATUS FOR ESTIMATING PARAMETER FOR SERVO MECHANISM, AND PARAMETER ESTIMATING METHOD AND PARAMETER ESTIMATING PROGRAM

摘要

To reduce a processing burden for parameter estimation and shorten a processing time.SOLUTION: A parameter estimating apparatus 1 of a servo mechanism generates known parameter information by using a normal model state locus, an abnormal state locus, and a changed state locus to store the known parameter information in a known parameter information storing unit 28, as pre-processing for parameter estimation. Upon estimation of parameters of the servo mechanism as an observation object, the apparatus generates an observed state locus which is a state locus of the servo mechanism as the observation object, and calculates differential vectors by using the observed state locus and a normal state locus obtained from an actual machine of the servo mechanism which normally operates, to estimate parameters by using the calculation result and the known parameter information.SELECTED DRAWING: Figure 2
