“…In [4], a robust pressure controller is designed and analysed under the quantitative feedback theory (QFT) control theory for the second‐order model. In the last few years, the Common Rail control technology has been extended to gasoline engines [5, 6]. In spite of the similar structure among the fuel systems of diesel engines and GDI engines, there are still plenty of differences.…”

This paper presents a novel approach for rail pressure control of GDI engines. The control objective is to make the rail pressure track the given reference. Different from the existing nonlinear controller design methods, the proposed procedure can be divided into 3 steps: 1) A steady state control is deduced, playing the similar role of the mapbased control strategy that widely used in automotive control; 2) A feedforward control is derived based on the reference dynamics; 3) A feedback control is also considered which can be rearranged into a state-dependent PID. The proposed method provides a concise derivation procedure and the structure is comparable to those widely used in modern automotive control. Finally, simulation results in the environment of commercial software AMESim with actual system parameters show the efficiency of the proposed approach.

“…Recently the CR injection technology, originally introduced for diesel engines, has been extended to gasoline engines Corno et al (2008); Tomforde et al (2008) in order to reduce pollutant emissions, as required by the more and more restrictive emission legislations, and improve engine performance perceived by customers. More in details, for spark ignition engines, the CR system is useful to reduce the exhaust emissions and fuel consumption and to improve the driving dynamics Achleitner et al (2007).…”

Gasoline Direct Injection (GDI) spark ignition engines equipped with the Common Rail (CR) system strongly improve engine performance in terms of fuel consumption and pollutant emission reduction. As a drawback the fuel pressure in the rail has to be kept as constant as possible to the demanded pressure working set-points in order to achieve the advantages promised by this technology. In this work a Model Reference Adaptive Control (MRAC) algorithm based on the Minimal Control Synthesis (MCS) strategy is proposed to reduce the residual pressure in the rail. Numerical results based on a CR mean value model, previously proposed in the literature and experimentally validated, show that a very satisfactory attenuation of the pressure ripple as well as pressure tracking are attained in different working conditions. A quantitative comparison with a classical gain scheduling model-based control approach confirms furthermore the effectiveness of the proposed adaptive control strategy.
