INTERNAL COMBUSTION ENGINE CONTROLLER

To provide a control device for an internal-combustion engine designed to ensure that required responsiveness is obtained as actual torque responsiveness with respect to a torque demand even when the torque responsiveness with respect to the actuation of a particular actuator is affected by the operating conditions. A response compensating filter 6 is provided at a preceding stage to an air inverse model 10, and the target torque which has been corrected by the response compensating filter 6 is converted by the air inverse model 10 to obtain a target opening degree of a throttle 2. A time constant kT o of the response compensating filter 6 is set on the basis of the operating conditions of the internal-combustion engine so that the responsiveness of actual torque with respect to the torque demand reaches a preset standard responsiveness.
