Abstract

In this paper a model-based control system for a diesel engine was developed. The control system consisted of two-degree-of-freedom (TDOF) controllers of air path system and combustion system. For the air path system, a physical model was developed and a feedforward (FF) controller was designed by an inverse model. A feedback (FB) controller was designed by using an H_∞ control theory. For the combustion system, a physical model was also developed and an FF controller was designed by an inverse model. An FB controller was designed based on an adaptive output feedback theory. The performance of the overall control system was evaluated by a reference follow-up test in a transient mode experiment. Here, the air path controller adjusted the boost pressure and external EGR ratio and the combustion controller adjusted specific points of heat release rate (HRR).
