模擬送電装置のパラメータ推定

Abstract

The optimal controls with the error of mesured parameter values are not sensitive enough. This paper presents a method to estimate the parameter values with accuracy for nonlinear system. The basic principle of the method is the algorithm that is based on weighted-least-squares estimation theory. The proposed method was used to estimate the parameters of the AC power system simulator. It is shown that the unknown parameters are estimated with accuracy within 30 iterations. The method was modified to process the two or more kinds of transient phenomenon data simultaneously, and good results were obtained.
