摘要目前出现的控制策略各式各样，由于插电式混合动力驱动系统的复杂性，建立被控对象的精确数学模型非常困难，传统控制策略在这些方面显得力不从心，而模糊控制不依赖于被控对象的精确数学模型，主要依据工程经验来制定控制规则，并且模糊算法在计算上也不是特别复杂，模糊控制策略显示出了良好的控制品质和应用前景。本文针对目前出现的插电式并联混合动力汽车控制目标作详细的归类和介绍，制定基于模糊逻辑的控制策略，用以保证发动机和电机的最佳扭矩分配，实现系统的总体效率最高，提高整车燃油经济性和排放性能。通过仿真比较证明模糊逻辑控制策略的优秀品质。21205

Matlab-based Drive and control system design of Plug in hybrid electric vehicle
Abstract
Currently a wide range of control strategies that appeared due to the complex plug-in hybrid drive system, the establishment of precise mathematical model of controlled object is very difficult to traditional control strategies in these areas appeared to be inadequate, and fuzzy control is not dependent on the accused accurate mathematical model of the object, based primarily on engineering experience to develop control rules and fuzzy algorithm is not particularly complicated in computation, fuzzy control strategy has shown good control quality and application prospects. In this paper, the present situation of the plug-in parallel hybrid electric vehicle control objectives for detailed classification and presentation, developing fuzzy logic-based control strategy to ensure optimal torque distribution to the engine and the motor to achieve the highest overall system efficiency, improveing vehicle fuel economy and emissions performance. Comparison shows excellent quality of fuzzy logic control strategy by simulation.
Fuzzy control is based on experiences, it is no need to know the math model which is in charge of, and it is easy to control the system not identified or non-linear, and is robust to an uncertainty system, and it can get rid of external noise. Fuzzy logic control has been widely used in the field of HEV, and the result of research can manifest the bright future of fuzzy logic control.
The design and research of parallel HEV fuzzy logic control strategy is based on parallel HEV driving system and HEV logic threshold control strategies, using the fuzzy logic control to complete the design of control algorithm. In this thesis, fuzzy logic control strategy has been systematically introduced and builded fuzzy logic control system for parallel HEV. Fuzzy logic control strategy according to different control target is designed and the simulation of the fuzzy logic control strategy .
