As one of the most important actuators for gasoline direct injection technology,common rail systems provide the requested rail pressure for fuel injection.Special system characteristics,such as coupled discrete-continuous dynamic in the common rail system,limited measurable states,and time-varying engine operating conditions,impel the combination of advanced methods to obtain the desired injection pressure.Therefore,reducing the pressure fluctuation and satisfying engineering implementation have become noteworthy issues for rail pressure control (RPC) systems.In this study,the benchmark problem and the design specification of RPC proposed by 2018 IFAC E-CoSM Committee are introduced.Moreover,a common rail system model is provided to the challengers,and a traditional PI control is applied to show the problem behaviors.Finally,intermediate results of the challengers are summarized briefly.
