Engine control system with actuator control

An engine control apparatus comprising:

• a target combustion parameter determining circuit which determines target values of a plurality of combustion parameters which represent combustion states of fuel in a combustion engine and are needed to achieve required performances of the combustion engine;
• a combustion parameter deviation calculator which calculates a combustion parameter deviation that is a deviation of an actual value of each of the combustion parameters from the target value thereof;
• a controlled parameter selector which selects at least one of controlled parameters correlating with the combustion parameters as a function of a degree of a selected one of the combustion parameter deviations for minimizing the selected one of the combustion parameter deviations, the controlled parameters being parameters for controlling operations of actuators working to control the combustion states of the combustion engine;
• and
• a combustion controller which controls the one of the controlled parameters, as selected by the controlled parameter selector, to minimize the selected one of the combustion parameter deviations.
