基于模糊控制的复合电源电动汽车建模与仿真

Modeling and Simulation of Hybrid Energy Electric Vehicle Based on Fuzzy Control

应用MATLAB和ADVISOR建立蓄电池、超级电容和DC/DC的仿真模型,依据实际经验对模糊控制的规则和论域进行设计;然后,将仿真模型和控制策略嵌入ADVISOR顶层模块,构建复合电源电动汽车整车模型,进而对整车性能进行仿真分析。以某款微型纯电动轿车为例,选取NEDC工况分别对单电源和复合电源进行模拟分析,结果表明:所构建的复合电源模糊控制策略可行有效,能延长蓄电池的使用寿命,增大续航里程,提升整车性能。

By means of MATLAB and ADVISOR,the simulation models of battery,super capacitor and DC/DC were constructed,and fuzzy control rules and domain were designed according to experience.Then,the simulation model and control strategy were embedded in ADVRISOR top-level module to build a composite power electric vehicle model,and the vehicle performance simulation was conducted.Taking a micro electric car as an example,the NEDC condition was selected for simulation analysis.The results show that the fuzzy control strategy is feasible and effective,the application of the composite power source can prolong the service life of the battery and increase the mileage,so the vehicle performance can be enhanced.
