PLANT AND INTERNAL COMBUSTION ENGINE CONTROL DEVICE

Title:

PLANT AND INTERNAL COMBUSTION ENGINE CONTROL DEVICE

Document Type and Number:

WIPO Patent Application WO/2006/049169

Kind Code:

A1

Abstract:

There is provided a plant and internal combustion engine control device capable of improving controllability and control accuracy when controlling a plurality of control amounts while eliminating interference between control inputs and control amounts. A plant (90) has interference between TH&lowbar cmd, Liftin&lowbar cmd as control input and PB, Gcyl as control amounts. The control device (1) of the plant (90) uses a predetermined control algorithm which combines a predetermined response-specifying type control algorithm (expressions (2) to (8)) and a predetermined non-interference control algorithm expression (9) based on a plant model (expression (20)) in which the plant (90) is modeled as a discrete time system model. The two control inputs TH&lowbar cmd and Liftin&lowbar cmd are calculated as two non-interference inputs eliminating interference so that PB and Gcyl follow the target values PB&lowbar cmd and Gcyl&lowbar cmd.
