Model based rail pressure control of GDI engine

This paper proposes a model–based rail pressure control (RPC) scheme for GDI (gasoline direct injection) engines. First, a control–oriented first–principle physics model is established for the rail pressure system. The backstepping technique is then used to derive a non–linear controller with guaranteed stability. For an engineering application, some compensations and corrections are further considered, such as input shaping, non–linear correction, anti–windup of integrator, battery voltage correction, etc. Finally, the proposed rail pressure controller is tested on the pump test rig and engine test bench. The results show the control performance is satisfactory.
