Abstract
An internal combustion engine includes an air charging system. A method to control the air charging system includes providing a desired operating target command for the air charging system, and monitoring operating parameters of the air charging system. An error between the desired operating target command for the air charging system and the corresponding one of said operating parameters of the air charging system is determined, and scheduled PID gains are determined based on the error utilizing a PID controller. An adaptive algorithm is applied to modify the scheduled PID gains, and a system control command for the air charging system is determined based upon the modified scheduled PID gains. The air charging system is controlled based upon the system control command for the air charging system.
