摘要： An apparatus for controlling the positioning of a throttle valve situated to control the amount of air permitted to enter an internal combustion engine operable in a plurality of control modes. The apparatus includes a driver responsive to a drive signal indicating a target throttle valve position for moving the throttle valve to the target throttle valve position, a sensor sensitive to the movement of the throttle valve for producing a digital sensor signal indicative of a sensed throttle valve position, and a control unit for producing the drive signal to bring the sensed throttle valve position into coincidence with the target throttle valve position. The disturbances introduced onto the driver and the sensor are estimated based on the target and sensed throttle valve positions. The target throttle valve position is corrected based on the estimated disturbances.
