System and method for engine transient power response

A method for controlling an engine, the method comprising:

• receiving a request signal indicative of a difference between a present power level output by the engine and a required power level for the engine;
• generating in response to the request signal a position control signal on the basis of the difference, the position control signal indicative of a first request for adjusting a present position of a variable geometry mechanism of the engine towards a commanded position proportionally to the difference to achieve the required power level;
• generating on the basis of the position control signal an acceleration rate control signal indicative of a second request for adjusting an acceleration rate of the engine in accordance with the commanded position of the variable geometry mechanism;
• and
• outputting the position control signal and the acceleration rate control signal to the engine.

A system for controlling an engine, the system comprising:

• means for receiving a request signal indicative of a difference between a present power level output by the engine and a required power level for the engine;
• means for generating in response to the request signal a position control signal on the basis of the difference, the position control signal indicative of a first request for adjusting a present position of a variable geometry mechanism of the engine towards a commanded position proportionally to the difference to achieve the required power level;
• means for generating on the basis of the position control signal an acceleration rate control signal indicative of a second request for adjusting an acceleration rate of the engine in accordance with the commanded position of the variable geometry mechanism;
• and
• means for outputting the position control signal and the acceleration rate control signal to the engine.
