ABSTRACT:
An engine with inertial integration and delay is controlled through the use of a disturbance estimator. Control logic includes a feed-forward control path driving a control input with a control signal. The feed-forward control path is designed to provide closed-loop control of the controlled parameter without the presence of transport delay. The disturbance estimator generates an estimate of the engine disturbance. A Smith predictor generates a compensation signal for the feed-forward control path based on the control signal and the engine disturbance estimate.
