基于模糊控制的纯电动汽车空调控制器的研究

Research on Air Conditioning Controller of Pure Electric Vehicle Based on Fuzzy Control

纯电动汽车具有能耗少,无排放污染,噪音低等优点,受到人们的越来越多的关注。但其因电池容量受限导致其续航里程短,这是限制其发展的重要因素之一,而车身电气附件的使用进一步减小了纯电动汽车的续航里程。空调系统是汽车的第二大耗能设备,它的工作效率将影响整辆汽车的性能和续航里程。本文基于模糊语言变量和模糊逻辑推理的智能控制方法,对纯电动汽车车空调控制系统的压缩机、鼓风机,混合风门,模式风门和循环风门等进行进行控制研究,控制系统所需的反馈信号由传感器测量和转换,控制系统比较并判断每个传感器收集的数据,以实现对空调压缩机转速的高效控制,增加续航里程,保证电动汽车的动力性能。

Pure electric vehicles have the advantages of low energy consumption,no emission pollution,low noise,etc.,which have attracted more and more attention.However,due to the limited battery capacity,its cruising range is short,which is one of the important factors limiting its development.The use of body electrical accessories further reduces the cruising range of pure electric vehicles.The air-conditioning system is the second most energy-consuming equipment in cars,and its work efficiency will affect the performance and cruising range of the entire car.Based on the intelligent control method of fuzzy linguistic variables and fuzzy logic inference,this paper conducts control research on the compressor,blower,hybrid damper,mode damper and circulation damper of the air conditioning control system of pure electric vehicles.The feedback signal required by the control system is determined by sensor measurement and conversion,and the control system compares and judges the data collected by each sensor to achieve efficient control of the air-conditioning compressor speed,increase the cruising range,and ensure the power performance of electric vehicles.
