PROBLEM TO BE SOLVED: To accurately acquire actual characteristics on the basis of one actual characteristic point.SOLUTION: An actual segment is acquired and actual characteristics are acquired on the basis of one actual characteristic point, initial characteristics, and a characteristic regulation relation. A gradient αis acquired from a segment βof the initial characteristics and an actual characteristic point P, a segment βis acquired on the basis of the gradient αand the characteristic regulation relation, and a first provisional line is acquired from the gradient αand the segment β. Subsequently, if the n-th provisional line is repeatedly acquired and end conditions are satisfied, a segment βn of the n-th provisional line is defined as the actual segment and the second provisional line is defined as the actual characteristics. As a result, it is possible to accurately acquire the actual characteristics as compared with a case of acquiring actual characteristics with the segment set as a fixed value.
【課題】1つの実特性点に基づいて実特性を正確に取得する。【解決手段】1つの実特性点と、初期特性と、特性規定関係とに基づいて、実切片を取得して実特性を取得する。初期特性の切片β0と実特性点Pとから勾配α1を取得し、勾配α1と特性規定関係とに基づいて切片β1を取得し、勾配α1と切片β1とから第1暫定直線を取得する。以下、第n暫定直線の取得を繰り返し、終了条件が成立した場合の第n暫定直線の切片βnを実切片として、第2暫定直線を実特性とする。その結果、切片を固定値として実特性が取得される場合に比較して、正確に実特性を取得することができる。【選択図】図9
