Abstract
A method of controlling a diesel engine that is capable of multiple combustion modes and equipped with a turbocharger and EGR loop. The control method avoids a singularity condition inherent in turbocharged diesel engine having multiple combustion modes. For different combustion modes, different system states, control variables, and actuators are carefully chosen for different controllers based on the characteristics of the corresponding combustion mode as well as sensor and measurement limitations.
