| Abstract: | This paper proposed model predictive control intelligent optimization strategies based on system model simplification for hybrid electric vehicles to deal with computation burden and on-line optimization problems in conventional control strategies. The 3 degrees of freedom system model was reduced to 1 degree of freedom system model. The model predictive control problem was solved using continuation/generalized minimum residual method. The simulation was conducted using MATLAB/ Simulink and GT-POWER co-simulation platform. The results showed that the proposed model simplification is effective, and the proposed model predictive control method can improve fuel economy significantly and can be implemented in real-time. |
