This paper proposes a common rail pressure controller for passenger car diesel engines. The common rail system of diesel engine has some difficulties to control rail pressure. The rail pressure is influenced by interaction between a metering unit (MeUn) and a pressure control valve (PCV). The interaction increases complexity of control algorithm. In order to solve this problem, we present a common rail pressure controller based on the quantitative feedback theory (QFT). For the controller design, a plant model of the common rail system is approximated by a first order transfer function, and the PCV driving current and the rail pressure are used as input/output variables of this model. The rail pressure variation by MeUn is represented as parametric uncertainty. Then, requirement specifications for stability and reference tracking are defined, and the control algorithm is designed to satisfy these requirements using the QFT method. In order to validate the proposed controller, engine experiments are performed. The QFT based rail pressure controller successfully satisfies the tracking performance. Furthermore, the control robustness is evaluated when the MeUn driving current is abruptly changed.
