| 英文摘要 |
| Focusing on plug-in hybrid electric vehicle (PHEV), a classical hybrid system, a model predictive control
(MPC) strategy based on mixed logical dynamical (MLD) model and vehicle speed prediction is proposed. Firstly, the
dynamic model of parallel plug-in hybrid electric city bus is established using the linearized energy consumption models
of engine and motor. Then, the driving intention is recognized through fuzzy inference, and a vehicle speed prediction
method using nonlinear auto-regressive (NAR) models neural network is proposed based on the driving intention and
the past vehicle speed data. Next, the MLD model is established with the objective function of minimum equivalent
fuel consumption, and the optimal motor torque sequence within the vehicle speed prediction horizon can be solved with
the predictive control theory. Finally, the simulation experiment is implemented, and the result shows that the proposed
energy control strategy can improve the PHEV fuel economy compared with electric assist strategy under certain driving
conditions. |
