| 摘 要： | 将动态规划应用于模型预测控制构架中,建立了基于空间域的插电式并联混合动力汽车燃油经济性预测控制数学模型。基于动态规划的插电式混合动力汽车全局优化控制的仿真表明,蓄电池荷电状态(SOC)基本上都是从行驶起点时的最大值逐渐减少到终点时的最小允许值,提出理论SOC参考斜率作为模型预测控制SOC的参考斜率,并以未来行驶工况中出现的特殊工况为依据对理论SOC参考轨迹进行修正。结果表明采用此方法能使模型预测控制策略的控制效果接近全局优化控制策略的计算结果,汽车油耗显著降低。

| Abstract: | The dynamic programming is applied to model predictive control configuration,and a predictive control mathematics model is established for the fuel economy of plug-in hybrid electric vehicles(HEVs) based on spatial-domain.A global optimal method for plug-in HEVs is studied with dynamic programming,and the results indicate that the state of charge(SOC) is reduced slowly from the maximum at a trip's initiation to the low threshold at the destination.The theoretical SOC slope is proposed to be taken as the ref... |
