To achieve accurate control of the transient air-fuel ratio for gasoline engines, a composite predictive control method based on wavelet network is proposed. The inverse system of transient air-fuel ratio system was to identify with wavelet network, which is able to dynamically compensate intake flow with feedforward control, and a pseudo-linear system is formed by cascading the inverse system with the original system. Then the dynamic matrix control(DMC) was used as a compensation for both internal and external disturbance in real time, and the effective control for transient air-fuel ratio s...
