Abstract
An engine with transport delay represented by a delay period is controlled with a controller in the feed-forward path and a compensator in a negative inner feedback loop around the controller. The controller generates a control signal so as to control the engine as if the engine was without the delay. A compensation signal is generated as the sum of the control signal only over the delay period. The control signal is based on an error signal generated as the difference between a desired input and the sum of a controlled engine output and the compensation signal.
