Summary:PROBLEM TO BE SOLVED: To improve a followup stability without the response delay of a torque motor (actuator). SOLUTION: An output duty outputting actually is set in response to a request duty based on the request current for a torque motor 19 for controlling the running state of an internal combustion engine 1. Meantime, in order to cope with the case in which the output duty in response to the request duty by the restriction on a circuit is not set, the current and its change flowing in the torque motor 19 at present based on the output duty are estimated. In other words, the output duty is converted to the output current in response to the electric source voltage value and the resistance value of the current route and estimated as an estimation current rightly by the application of an anneal (smoothening) process in response to the inductance of the coil of the torque motor 19. Therefore, the output duty can be coincided with the request duty and the response delay of the torque motor 19 is compensated and the followup stability is improved.
