Abstract
This paper proposes a closed loop multivariable EGR/Spark timing management system for maximum dilution control while maintaining a desired level of combustion stability. A combustion stability measure derived from in-cylinder ionization signals is used as feedback. An extremum seeking algorithm is employed to modulate spark timing in a slow-time scale in order to maximize the steady-state EGR amount. Simulation results based on data collected from a 3.0L V6 engine are also included to illustrate the proposed control strategy
