CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE

摘要

A control device for an internal combustion engine includes an in-cylinder pressure detector, an output shaft torque calculator, a target torque calculator, an input torque parameter calculator, and a controller. The output shaft torque calculator is to calculate an output shaft torque of an output shaft of the internal combustion engine based on an in-cylinder pressure. The target torque calculator is to calculate a target torque of the output shaft torque. The input torque parameter calculator is to calculate an input torque parameter representing an input torque such that the output shaft torque becomes equal to the target torque using a feedback control algorithm which is based on a controlled object model which models a controlled object that receives the input torque parameter as input and produces the output shaft torque as output. The controller is to control the output shaft torque using the input torque parameter.

1. A control device for an internal combustion engine, comprising:
an in-cylinder pressure detection unit that detects an in-cylinder pressure which is a pressure inside a cylinder of an internal combustion engine; an output shaft torque calculation unit that calculates an output shaft torque which is a torque of an output shaft of the internal combustion engine based on the detected in-cylinder pressure; a target torque calculation unit that calculates a target torque serving as a target of the output shaft torque of the internal combustion engine; an input torque parameter calculation unit that calculates an input torque parameter representing an input torque such that the detected output shaft torque becomes equal to the calculated target torque by using a predetermined feedback control algorithm which is based on a controlled object model which models a controlled object that receives the input torque parameter as input and produces the output shaft torque as output; and a control unit that controls the output shaft torque of the internal combustion engine using the calculated input torque parameter.
