| Abstract: | For the problem of air-fuel ratio (AFR) variation caused by the air charge changing in the gasoline engine, a PID-based feedback controller is designed to guarantee that the AFR can converge to the ideal value quickly. First, a model-based air-charge estimation algorithm is proposed. With this estimation, a feedforward controller is designed. Then, the fuel injection regulation is realized by combining the feedforward controller and the PID feedback controller. The performance of the control system is evaluated with a simulator constructed with experimental data. Finally, the control scheme is validated on a real-time engine control test bench. |
