Document Type and Number:
Japanese Patent JP3316955
Kind Code:
B2
Abstract:
In order to optimally suppress effects of error exerted upon control results by any modeling error which may arise from load fluctuations or the like of the internal combustion engine approximated as a dynamic model under an advanced control theory, present and past values of an operating quantity and control quantity which correspond respectively to a control input and control output of an internal combustion engine are utilized as state variable quantities representing the internal state of the dynamic model of an internal combustion engine. Furthermore, the target value and difference are accumulated for the foregoing control quantity. Modeling of the internal combustion engine is performed in realtime, and optimal feedback gain is calculated periodically or under certain specified conditions for a regulator constructed on the basis of these model constants calculated in realtime. The operating quantity for the internal combustion engine is determined on the basis of this calculated optimal feedback gain, the foregoing state variable quantities, and the foregoing accumulated difference value.
