: This paper presents a robust air-to-fuel ratio (AFR) control algorithm for managing exhaust gas recirculation (EGR) systems. In order to handle production tolerance, deterioration and parameter-varying characteristics of the EGR system, quantitative feedback theory (QFT) is applied for designing the robust AFR control algorithm. A plant model of EGR system is approximated by the first order transfer function plus time-delay (FOPTD) model. EGR valve position and AFR of exhaust gas are used as input/output variables of the plant model. Through engine experiments, parameter uncertainty of the plant model is identified in a fixed engine operating point. Requirement specifications of robust stability and reference tracking performance are defined and these are fulfilled by the following steps: during loop shaping process, a PID controller is designed by using a nominal loop transmission function represented on Nichols chart. Then, the frequency response of closed-loop transfer function is used for designing a prefilter. It is validated that the proposed QFT-based AFR control algorithm successfully satisfy the requirements through experiments of various engine operating points.Key words : Passenger car diesel engine(승용디젤엔진), Exhaust gas recirculation(배기가스 재순환), Quantitative feedback theory(정량적 피드백 이론), Air-to-fuel ratio control(공연비 제어), Robust control(강인 제어) AFRexh : air-to-fuel ratio of exhaust gas [-] AFRexh,des : desired air-to-fuel ratio of exhaust gas [-]

“…We do not give any detail about the derivation of such controllers. Some intake manifold BGR controllers are given in Jankovic and Kolmanovsky (1998), Van Nieuwstadt et al (2000) or Chauvin et al (2008). Some VVA actuators controllers can be found in Chauvin and Petit (2007) or Genç et al (2001).…”

“…In the engine under consideration, there are two ways of admitting burned gases inside the cylinder. On the one hand, the LP EGR circuit permits to manage the BGR in the intake manifold by actuating both the EGR and the exhaust valves (see Jankovic and Kolmanovsky (1998), Chauvin et al (2008)). Because of the length of the EGR circuit, the intake manifold BGR has a large response time (see Throop and Cook (1985)).…”

This paper addresses the problem of cylinder burned gas rate transient control of VVA equipped Diesel engines. This problem is of importance for NO x emissions reduction. The proposed strategy coordinates existing low-level intake manifold burned gas rate and VVA controllers. To determine relevant control actions, a model of cylinder filling phenomenon is determined. It expresses, under the form of a discrete event dynamics, the behavior of the cylinder burned gas rate at intake valve closure. Interestingly, the model is invertible, thanks to its analytical nature. This property directly suggests an inverse formula that serves as control law. The strategy is efficient as is highlighted by experimental results obtained on a 1.6 L Diesel engine test bench. As a result, NO x emissions are largely diminished during transients.

“…The air flow is measured but the main difficulty is estimating the two EGR flows in any possible combination: -a single HP EGR flow, -a single LP EGR flow or, -simultaneous HP and LP EGR flows. Some work has been reported on the intake composition estimation in HP EGR loop configuration (open-loop observer [10] and closed-loop observer [8]). The basis of these two estimators can be transposed to the LP EGR system with the same configuration in terms of sensors.…”

Résumé -La simulation comme support pour les problématiques en contrôle dans le cadre des boucles d'air Diesel modernes -Il semble désormais évident que la boucle d'air des moteurs Diesel va devoir améliorer ses performances pour atteindre des conditions dans la chambre qui soient compatibles avec une baisse significative des émissions en sortie moteur. Cet axe important passe par l'évolution de la boucle d'air vers des systèmes plus complexes basés sur des technologies avancées comme la distribution variable ou la double suralimentation. Dans ce contexte de complexité croissante, la contrôlabilité du moteur devient un critère de premier ordre dans le choix des orientations technologiques. Grâce à une grande flexibilité d'architecture, à la possibilité de représenter correctement les tendances et à un couplage aisé avec le contrôle moteur, la simulation 0D propose un support très intéressant pour aider ces développements et participer à l'identification des meilleures solutions de boucles d'air Diesel. Ce papier présente la façon dont la simulation est devenue un outil clé pour développer le contrôle moteur sur différents types de boucle d'air avant même d'avoir un moteur disponible au banc afin d'anticiper les points durs et de commencer à évaluer la contrôlabilité des différentes technologies dès les premières étapes du processus de développement moteur. Abstract -Simulation Support for Control Issues in the Context of Modern Diesel Air Path Systems -It is now obvious that the air path system will have to increase its performance to manage the in-cylinder conditions required by the combustion process if significant raw emission reduction is expected in Diesel engine applications. This crucial issue means air path evolutions with complex systems including advanced technologies such as
