“…Only the larger steps (e.g., from −2 to 4 and from 4 to −3 in Fig. 6) took around 15 cycles, which compares well with previously published results [8], [1]. The inlet valve closing showed to be a sufficient control signal in many operating points.…”

“…As HCCI lacks direct actuation over the combustion phasing, much work has been devoted to designing controllers capable of setpoint tracking and disturbance rejection. Ignition timing in HCCI engines is determined by several factors [1] including the auto-ignition properties of the air-fuel mixture, the intake temperature, the amount of residual gases in the cylinder, etc. As a consequence, there are many possible choices of control signals, such as [1] variable valve timing, intake temperature, and the amount of residuals trapped in the cylinder.…”

Abstract-This paper presents experimental results on model predictive control of the combustion phasing in a Homogeneous Charge Compression Ignition (HCCI) engine. The controllers were based on linearizations of a previously presented physical model of HCCI including cylinder wall temperature dynamics. The control signals were the inlet air temperature and the inlet valve closing. A system for fast thermal management was installed and controlled using mid-ranging control. The resulting control performance was experimentally evaluated in terms of response time and steady-state output variance. For a given operating point, a comparable decrease in steadystate output variance was obtained either by introducing a disturbance model or by changing linearization point. The robustness towards disturbances was investigated as well as the effects of varying the prediction and control horizons.

“…This means that HCCI lacks direct actuation over the combustion phasing, making combustion phasing control a challenging control problem. Ignition timing in HCCI engines is determined by several factors including the auto-ignition properties of the air-fuel mixture, the intake temperature, and the amount of residual gases in the cylinder [1]. As a consequence, there are many possible choices of control signals, such as variable inlet and exhaust valve timing, intake temperature, etc.…”

“…Among these, [5,20,21,26,28,39,42] can be mentioned. The standard procedure for creating a controller includes the modeling part as the first step [1,6,27,38,40]. Often these models differ in several aspects from models which include details of the combustion process, like three-dimensional Computational Fluid Dynamics (CFD) models [4,7,32,33].…”

Résumé -Méthode de développement de lois de commande pour la combustion PCCI basée sur la simulation système -Cet article présente une méthodologie de développement de lois de commande pour la combustion PCCI. La méthode proposée repose sur l'utilisation d'un simulateur du moteur dont le niveau de représentation est adapté aux besoins de l'application ciblée. Le simulateur proposé repose sur l'association d'un modèle de combustion multidimensionnel (pour la partie haute pression du cycle moteur) et d'un modèle à valeurs moyennes (pour la description des d'échanges gazeux). L'association des caractéristiques de ces modèles permet d'aboutir à un niveau de représen-tation suffisamment précis pour accompagner le développement de lois de commande. De plus, les simplifications réalisées permettent des gains conséquents en termes de temps de simulation. Cet article propose aussi une simplification supplémentaire en introduisant une méthode d'identification d'un modèle de Wiener. Les résultats présentés dans cette publication sont le fruit des travaux du centre de recherche « SFB 686 -Modellbasierte Regelung der homogenisierten Niedertemperatur-Verbrennung » de l'Université RWTH d'Aix-la-Chapelle et de l'Université de Bielefeld en Allemagne. Abstract -A Dynamic Simulation Strategy for PCCI Combustion Control Design -Subject of this work is a dynamic simulation strategy for PCCI combustion that can be used in closed-loop control development. A detailed multi-zone chemistry model for the high-pressure part of the engine cycle is
