Control device for internal combustion engine

A control device for an internal combustion engine, comprising:

• an in-cylinder pressure detector to detect an in-cylinder pressure inside a cylinder of the internal combustion engine;
• an output shaft torque calculator to calculate an output shaft torque of an output shaft of the internal combustion engine based on the in-cylinder pressure;
• a target torque calculator to calculate a target torque of the output shaft torque;
• an input torque parameter calculator 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;
• and
• a controller to control the output shaft torque using the input torque parameter.
