In this paper, a combined feedforward and feedback control for start-up engine control is proposed. In the proposed control method, the feedforward control input is searched by a numerical optimization method called PSO (particle swarm optimization) and the feedback control is realized by GPC (generalized predictive control) based on JIT(just in time) modeling of local plant model. The validity of...
Because the oxygen sensor is installed into the vent-pipe of gasoline engine, the air fuel ratio signal of gasoline engine exists transmission delay, which affects the control accuracy of air fuel ratio if using directive air fuel ratio sensor signal. To overcome air fuel ratio transmission delay affection, a new air fuel ratio predictive control method was provided using adaptive expanded particle...
