INTERNAL COMBUSTION ENGINE CONTROL APPARATUS AND METHOD

Title:

INTERNAL COMBUSTION ENGINE CONTROL APPARATUS AND METHOD

Document Type and Number:

WIPO Patent Application WO/2013/001844

Kind Code:

A1

Abstract:

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.
