Résultats de l'Intégration du Cycle Thermodynamique (Contrôle Inverse)

Description de la Stratégie de Contrôle

Le solveur Newton-Raphson a calculé la racine d'un système couplé (MIMO) contenant à la fois les équations résiduelles des puces physiques et les variables du contrôle :

  • Objectif (Constraint) : Atteindre un Superheat de l'évaporateur fixé à la cible exacte (Surchauffe visée).
  • Actionneur (Bounded Variable) : Modification dynamique de l'ouverture de la vanne (valve_opening) dans les limites [0.0 - 1.0].

✅ Modèle Résolu Thermodynamiquement avec succès en 1 itérations de Newton-Raphson.

Validation du Contrôle Inverse

Variable / ContrainteValeur Optimisée par le Solveur
🎯 Superheat calculé à l'Évaporateur400.73 K (Cible atteinte)
🔧 Ouverture Vanne de Détente (Actionneur)0.3846 (entre 0 et 1)

Note : La surchauffe (Superheat) est calculée numériquement d'après l'enthalpie de sortie de l'évaporateur et la pression d'évaporation. L'ouverture de la vanne a été automatiquement calibrée par la Jacobienne Newton-Raphson pour satisfaire cette contrainte exacte !

Résultats de l'Intégration du Cycle Thermodynamique (Contrôle Inverse)

Description de la Stratégie de Contrôle

Le solveur Newton-Raphson a calculé la racine d'un système couplé (MIMO) contenant à la fois les équations résiduelles des puces physiques et les variables du contrôle :

  • Objectif (Constraint) : Atteindre un Superheat de l'évaporateur fixé à la cible exacte (Surchauffe visée).
  • Actionneur (Bounded Variable) : Modification dynamique de l'ouverture de la vanne (valve_opening) dans les limites [0.0 - 1.0].

✅ Modèle Résolu Thermodynamiquement avec succès en 1 itérations de Newton-Raphson.

🔧 Ouverture Vanne de Détente (Actionneur)0.3846 (entre 0 et 1)

Note : La surchauffe (Superheat) est calculée numériquement d'après l'enthalpie de sortie de l'évaporateur et la pression d'évaporation. L'ouverture de la vanne a été automatiquement calibrée par la Jacobienne Newton-Raphson pour satisfaire cette contrainte exacte !
