The piston stop position is crucial for instantaneous reverse starting method in idle-stop system. It is very difficult to control the piston stop position. In this paper, the relationship between the piston stop position and the air inflow is set up. Then the piston stop position control problem is converted to the electronic throttle control problem. A feedforward-feedback controller for the piston stop position of the GDI engine is proposed. The feedforward controller is spring compensator and friction compensator, which can eliminate the nonlinearity error of throttle system. The feedback controller is backstepping controller which is adaptive for a class of nonlinear processes. The simulation results show that the composite control law enables the throttle opening to track input orders quickly and accurately. And there is no overshoot.
