Abstract: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 consid… Show more
