要約
(EN)
A control apparatus (57) is a 2-input, 2-output integral-type optimal servo system in which intake air amount and intake oxygen concentration are used as control quantities (y1, y2) and the degree of opening of a control valve of an exhaust gas recirculation apparatus and the degree of opening of a control valve of a supercharger equipped with a variable flow rate mechanism are used as manipulated quantities (u1, u2), and includes an output feedback system. The control apparatus (57) is provided with an EGR valve opening degree control unit (70) and an opening degree control unit (72) for a variable flow rate valve of the supercharger. Each of the control units includes a non-interference controller (64) for eliminating interference between the manipulated quantity for the control valve of the exhaust gas recirculation apparatus and the manipulated quantity for the control valve of the supercharger equipped with the variable flow rate mechanism.
(FR)
Un appareil de commande (57) est un servosystème optimal du type intégré à 2 entrées, 2 sorties dans lequel la quantité d'air d'admission et la concentration en oxygène d'admission sont utilisées comme quantités de commande (y1, y2) et le degré d'ouverture d'une soupape de commande d'un appareil de recirculation des gaz d'échappement et le degré d'ouverture d'une soupape de commande d'un compresseur d'alimentation équipé d'un mécanisme à débit variable sont utilisés comme quantités manipulées (u1, u2), et comprend un système de rétroaction. L'appareil de commande (57) est pourvu d'une unité de commande (70) du degré d'ouverture de soupape EGR et d'une unité de commande (72) du degré d'ouverture destinée à une soupape à débit variable du compresseur d'alimentation. Chacune des unités de commande comprend un dispositif de commande de non-interférence (64) destiné à supprimer l'interférence entre la quantité manipulée pour la soupape de commande de l'appareil de recirculation des gaz d'échappement et la quantité manipulée pour la soupape de commande du compresseur d'alimentation équipé du mécanisme à débit variable.
