Abstract
(EN)
The present invention relates to an improved INA feedforward control method for a post-combustion CO2 capture system. By means of identifying a controlling variable and a controlled variable of a post-combustion CO2 capture system, an improved INA method is designed, and the integrated design of an improved INA and a feedforward controller is completed, thereby realizing the control of a CO2 capture rate y1 and a reboiler temperature y2. After being applied to a post-combustion CO2 capture system, the present invention can quickly and stably track a changing CO2 capture rate set value, effectively suppresses the effect of smoke disturbance and has a good anti-interference capability.

La présente invention concerne un procédé de commande prédictive INA amélioré pour un système de capture de CO2 post-combustion. Au moyen de l'identification d'une variable de commande et d'une variable commandée d'un système de capture de CO2 post-combustion, un procédé INA amélioré est conçu, et la conception intégrée d'un INA amélioré et d'un dispositif de commande prédictive est achevée, ce qui permet de réaliser la commande d'un taux de capture y1 de CO2 et d'une température de rebouilleur y2. Après avoir été appliqué à un système de capture de CO2 post-combustion, la présente invention peut suivre rapidement et de manière stable une valeur de consigne de taux de capture de CO2 changeante, supprime efficacement l'effet de perturbation de la fumée et présente une bonne capacité anti-interférence.
