Abstract
An electronic throttle control system including a throttle valve for adjusting the amount of air drawn into the engine is disclosed. A throttle valve is controlled by a throttle position feedback controller which suspends an integration element when position error absolute value is greater than a threshold, or when the position rate absolute value is greater than another threshold. The integration element includes an integration increment such that generation of the integration increment begins by a determination made of the position error between the throttle position and the position command. Once a determination of the sign of position error is made, a gain is applied to the position error. Also, a gain is applied to the sign of position error. The integration element of the throttle position feedback controller then operates with the position error and the sign of position error. The throttle valve then reacts in response to the throttle position feedback controller.
