計測不可能な入力の推定機能をもつ最小次元状態推定器による外乱抑制制御

抄録

A compensator with a function of estimating unmeasurable inputs based on a full-order observer has been already proposed. However, it seems very difficult to synthesize the compensator based on the minimal-order observer, because the innovation is equal to zero. In this paper, a novel synthesis method of the compensator based on the minimal-order observer is studied. The basic design idea is based on the fact that the full-order observer can be decomposed into the minimal-order observer and the output estimator.
