An LFT Approach toH$_{\infty}$ Control Design for Diesel Engine Common Rail Injection System

Abstract

Résumé -Une approche LFT pour la commande H ∞ des systèmes d'injection "Common rail'' des moteurs Diesel -Dans cet article, une approche LFT est proposée pour concevoir un contrôleur H ∞ LPV à temps-discret incluant une compensation anti-saturation. Cette méthodologie est appliquée au système d'injection "Common Rail" des moteurs Diesel à injection directe. L'efficacité de ce contrôleur est mise en avant en le comparant à l'aide de simulations avec un régulateur de type PID à gain séquencé embarqué sur véhicule.

Neural Predictive Controller Based Diesel Injection Management System for Emission Minimisation

“…A linear fractional transformation (LFT) was proposed by Gauthier et al (2007) which was applied to control diesel engine with common rail injection system and it is compared with Proportional-Integral-Derivative controllers. The control design consists of two parts as H∞ (infinity) LFT control design and the anti-windup compensator design.…”

Model-based analysis of injection process parameters in a common rail fuel supply system

“…One of the most fundamental works in this area is [2], in which the authors -as some of the first to do so -dealt with the fuel flow and control of injectors. In turn, in [4] a model of the overflow valve controlling the fuel pressure was developed, as well as a model of the fuel throttle valve in the high-pressure pump, which also considered a sub-model of that pump. The latter was controlled by a pseudo-random binary sequence.…”
