Abstract
An imbedded control system is disclosed for use with an engine having a combustion chamber and an associated piston. The control system may have at least one sensor configured to generate a signal indicative of a combustion process occurring inside the combustion chamber, and a controller in communication with the at least one sensor. The controller may be configured to determine an amount of heat and a pressure generated inside the combustion chamber based on the signal and a combustion model, to determine a heat flux through the piston based on the amount of heat and a heat flux model, and to determine a temperature at a rim of the piston based on the heat flux and a thermal model. The controller may be further configured to track a time at the temperature and the pressure, and to determine a damage count of the piston based on the time.
