PARAMETER IDENTIFICATION METHOD OF SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a parameter identification method capable of accurately identifying a parameter of a system in which a load external force is present.SOLUTION: A parameter identification method of a system identifies a parameter for regulating a response in a two-inertia system comprising a first inertia system configured by a drive motor 1 and a second inertia system that is connected to the first inertia system and in which a load external force is applied from the outside. In the parameter identification method, the two-inertia system is expressed by such an identification object model that input is the load external force and output is the rotation frequency of the drive motor 1; a pulse transfer function constituting the identification object model is expressed by a parameter for regulating a response; and a parameter for regulating a response is identified so that an error function comprising the input value to the identification object model and the pulse transfer function becomes minimum.
