Description
(実施例1)
本発明の実施例1について、配管および原料の送液制御の基本的な構成を図1に示す。本実施例は、マイクロリアクタ(反応器)内で原料Aと原料Bを混合あるいは反応させ、生成物Cを得るための2原料1ステップ反応あるいは混合のプロセスの例である。
図6でシステム同定部119aでのシステム同定の一例を説明する。図6に示されている実施例2では、各送液ラインの入力側の制御弁118を一つづつ順次(時分割的に)短時間だけオープン(全開)して送液していき、そのときの各送液ラインの流量qの応答をすべて同時に分配流量検知手段117で測定する。この測定は、定期的に実施される。図6で、u* 1〜u* nは、各送液ラインの入力のオープン信号を示し、q* 1〜q* nは各送液ラインの流量を示す。図6の測定結果では、各送液ラインの送液が他の送液ラインの流量qに影響を及ぼしているのが分かり、本プラントは経年変化により干渉型の多入出力システムになっている。
