摘要
基于Advisor建立了动力电池和超级电容的复合电源仿真模型,基于Matlab/Simulink设计了复合电源能量管理的模糊控制策略,并嵌入到仿真软件Advisor中。在UDDS工况下对模糊控制策略和逻辑门限控制策略进行了对比仿真。结果表明:相比于传统的逻辑门限控制方法,所建立的模糊控制策略能够减少大电流对电池的损害,充分发挥超级电容"削峰填谷"的作用,DC-DC逆变器工作效率从84.79%提高到88.92%,整车的能量消耗降低了6.45%。
The simulation model of the composite power of battery and ultra-capacitor for the electric vehi-cle was established based on Advisor. The fuzzy control strategy of the power distribution of the compositepower was designed in Matlab/Simulink and embedded into Advisor software. The simulation of the fuzzycontrol strategy and logic threshold control strategy were carried out under the working condition ofUDDS. The simulation results show that the fuzzy control strategy can ensure the battery avoiding hugecurrent and make the ultra-capacitor work effectively. The efficiency of the DC-DC converter is in-creased from 84.79% to 88.92%, and the total energy consumption was reduced by 6.45%.
