Abstract
Official abstract text for this publication.
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 unit ( 70 ) and an opening 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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A control apparatus for an internal combustion engine which comprises an exhaust gas recirculation device and a supercharger equipped with a variable flow rate mechanism, wherein the control apparatus is configured to be a 2-input, 2-output integral-type optimal servo system which uses an intake air amount and an intake oxygen concentration as a controlled variable and an opening of a control valve of the exhaust gas recirculation device and an opening…
