Description
c. 新しい制御および新しい予測状態経路をもたらすために現在の状態から始めて制御計算を繰り返すステップ。
次に図1Bを参照すると、現在のシステム状態に基づいて操作変数軌跡および有効制約のセットを最適化する費用関数を決定するために使用されるプロセス10Bが図示されている。
c. ニュートンステップに沿って最も近い限界制約まで移動し、ニュートンステップをフルステップの残りとみなす(55)。
一代替実施形態によれば、反復の数を低減し、収束を改善するためにウォームスタートが使用される。他の実施形態によれば、単純制約は、操作変数(アクチュエータなど)のためにハード制約に分割され、残りの制約(システム状態、システム出力など)は、ソフト制約として公式化される。他の実施形態では、最適化問題は
次に図2を参照すると、制御装置110の制御下における被制御システム100の簡略ブロック図が示されている。制御装置110は、コンピュータシステム90、出力モジュール112、および入力モジュール114を含む。動作中は、制御装置110は、モジュール112から操作変数(MV)のシーケンス120を生成し、入力モジュール114から被制御変数および外乱変数(入力変数)のシーケンス130を受信する。制御出力120、および入力130は、被制御システム100に送信されるまたはそれから受信されるアナログまたはデジタル制御信号の形を取ることができる。
