Abstract

This paper presents the control design and experimental results of an electronic fuel injection system of a diesel engine with a rack actuator. The control system has a cascade structure and consists of rack position control and engine speed control loops. A decomposition-based robust/adaptive control method is utilized for rack position control, and a fuzzy-PID control scheme is developed for the engine speed control. The proposed control system has been implemented on a diesel engine, and experimental results have demonstrated high performance of the developed control system for all working modes of the engine in the presence of model uncertainties such as spring deformation, fuel temperature variations and unmodeled friction.
