Abstract
An electronic control for a variable displacement turbocharger (VGT) determines the desired operation of the VGT in accordance with vehicle and engine operating conditions, and positions the VGT control arm to achieve the desired operation. When the engine is operating in a vacuum mode, the control arm is adjusted in open loop fashion; when the engine should be operating in a boost mode, the control arm is adjusted in a closed loop fashion according to the difference between the actual and desired boost.
