周波数重み付き平衡実現によるH²最適制御器の低次元化

抄録

In this paper, we propose a new controller reduction method which considers maintaining the index value of H²-optimal controller. In the method, a frequency-weighted balanced realization technique developed by Enns is employed to obtain low order controllers. The fractional representation is used to reduce the order of unstable controllers effectively. To illustrate the effectiveness of our method, two numerical examples are presented.
