Abstract :
This document describes a model-based controller for a high-pressure fuel system on a direct injection engine. This controller drives a high-pressure fuel pump with an inverse pump model and keeps injection pressure under control with a disturbance observer and a proportional (P) controller. The designed controller is a two-degrees-of-freedom control that can improve step response time and nominal pulsation at the same time. The effectiveness of the proposed method is investigated using real engine experiments and produces successful results compared with a PI controller.
