Description
本発明の別の態様は、ブロックのそれぞれによって受信される値の置換信号値(sig)を生成する信号発生器を用いてブロックの各入力ポートを増強することによってブロック図にわたるすべての信号リンクを弾性リンクに置き換えることにより、ブロック図として表される非線形システムの分散モデル同定の改良された方法を提供することである。
Claims (2)
- 複数の相互接続されたアトミックブロック(A、B)を有するブロック図(200)によって表される非線形システムの分散モデルを最適化する方法であって、前記アトミックブロックの各々は、対応する信号リンクを介して入力信号を受信するための少なくとも1つの入力ポートを含み、各アトミックブロックは前記非線形システムのサブシステムを表し、該方法(300)は、
前記ブロック図(200)中の少なくとも一部の信号リンクを弾性リンクに置き換えるステップであって、各弾性リンクが、対応する入力ポートを、前記入力信号に置き換わる置換信号(sig)を生成する信号発生器を用いて増強し、前記置換信号は、未知の時間関数であり、前記対応するアトミックブロックの変域に制限される、ステップと、
各弾性リンクについて、前記ブロック図(200)における前記入力ポートによって受信される前記入力信号と前記置換信号(sig)との間の差分を計算するステップと、
各弾性リンクについて、前記差分を補助信号として出力するステップと、
前記分散モデルの最適化のために、前記複数のアトミックブロック(A、B)の前記ポートのそれぞれからの前記補助信号を大域コスト関数において用いるステップと
を含む方法。 - 前記大域コスト関数は、前記分散モデルの最適化中に前記補助信号をゼロに向けて最小にするように構成される請求項1に記載の方法。
