1. An engine control system comprising:
- at least two actuators wherein the at least two actuators regulate one or more engine variables, the number of engine variables being less than the number of actuators; and
at least one controller operative to apply inputs to the at least two actuators to evaluate a response of the actuators, wherein the at least one controller is further operative to use the response for simultaneous feedforward control of the actuators for control of the engine variable.

Abstract
A method for controlling an engine output with at least two actuators, including applying inputs to actuators which regulate a variable of an engine, evaluating the response of the system, determining the ability of the actuators to change the engine variable, determining the capability of the actuators to reject a disturbance, calculating an optimum actuator feedforward control function based upon the ability and capability determined and controlling the actuators using the calculated function and a feedforward control algorithm.
