The precise control of rail pressure in GDI engines is an important issue. To reduce the workload of calibration and enhance the robustness in automotive product development process, a model-based controller design method is presented in this paper. A control-oriented fuel rail system nonlinear dynamics model, involving the high pressure pump, the fuel rail and the injectors, is established. The backstepping technique is used to derive a nonlinear rail pressure controller for the simplified model. The simulation results with MATLAB/Simulink demonstrate the effectiveness of the proposed control scheme, and control precise and response satisfy the design requirements.
