PROBLEM TO BE SOLVED: To provide a control device for an internal combustion engine capable of converting a demand air quantity G and a demand intake pressure P using an accurate intake system model in the control device for the internal combustion engine that computes demand torque T from the accelerator operating quantity of a driver, a demand air quantity G from the demand torque, the demand intake pressure P from the demand air quantity G, and throttle opening from the demand intake pressure P in regular sequence. SOLUTION: In this control device, a model error of an intake system model is learned. In the step S106, the relation between the demand intake pressure P and demand air quantity G is computed using the intake system model. In the steps S107, 108, the sensor output values of the actual intake pressure Pact and actual air quantity Gact are read. In the step S109, the model error of the intake system model is computed on the basis of the relation between the actual intake pressure Pact and actual air quantity Gact and the relation between the demand intake pressure P and demand air quantity G.
