基于小波变换-模糊控制的复合电源能量管理
Energy Management in Composite Power Supply Based on Wavelet Transform and Fuzzy Control
摘要
Abstract
Focusing on a hybrid electric vehicle equipped with a lithium battery and supercapacitor,the paper establishes a real-time wavelet transform-fuzzy control energy management control strategy.The objective is to enable the supercapacitor to handle high frequency signals at a reasonable state of charge(SOC)and the lithium battery to manage low frequency signals,all under the premise of satisfying dynamic performance requirements.Secondly,the vehicle model was developed based on Matlab/Simulink and ADVISOR software,and simulation tests were carried out under NEDC cycle conditions.The simulation results show that,compared with the single lithium battery,the peak driving current of the lithium battery in the composite power supply is reduced by 20.68%and its lifespan is increased by 16.75%under the wavelet transform-fuzzy control strategy.Finally,a scaled-down experimental platform of the composite power system was built and tested under NEDC conditions.The experimental results show that the proposed control strategy effectively manages the energy of the hybrid electric vehicle.关键词
