| Abstract: | The parameter of PID controller of air-fuel ratio in transient conditions is set by BP neural networks. AMESim simulation model of engine combustion and fuel supply system is established, BP neural network PID simulation module of air-fuel ratio control system is designed by MATLAB/Simulink and simulated dynamically in AMESim. The simulation experiment shows that the control strategy has good adaptive performance. Compared with the classical PID control, it can improve the stable supply of transient fuel and realize the accurate control of the air-fuel ratio. |
