中文摘要：
应用T—S模糊模型和MATLAB模糊控制工具箱设计了基于模糊逻辑的并联式混合动力汽车CFA6470PHEV的能量控制系统，并将其分为能量回馈制动控制系统和正常行驶时的能量控制系统，使控制系统的结构得以简化，有利于控制策略的制订。在控制策略制订后，使用T—S模糊控制模型，使能量回馈制动系统的输入输出量之间的关系非常明确；而对于正常行驶时的能量控制系统，既简化了输入输出量之间的关系，又可使发动机在最优工况范围内工作，使起动电机和驱动电机按预定的模式高效运行。仿真结果表明，所设计的能量控制系统合理可行。
英文摘要：
A fuzzy-logic-based energy management system for CFA6470 parallel hybrid electric vehicle is designed by employing T-S fuzzy model and the fuzzy control toolbox in MATLAB, and the system is then divided into energy regeneration control system and the energy management system in normal driving mode, thus the control system is simplified, conducive to the formulation of control strategy. Once the control strategy is set up, using T-S fuzzy model makes the relation between inputs and outputs becomes much clearer in energy regeneration control sys- tem. As for the energy management system in normal driving mode, it not only simplifies the relation between inputs and outputs, but also assures the engine working in the optimal region with the starter and driving motor efficiently operating in predefined modes. The simulation results indicate that the energy management system designed is reasonable and feasible.
