Abstract

The Energy Management System (EMS) is critical for electric vehicle (EV) in order to optimize energy consumption, improve efficiency, and enhance vehicle performance. The EMS provides the optimization of energy distribution among various vehicle components, reduces energy losses and maximizes the vehicle's efficacy. The EMS reduces battery stress to prevent excessive charging and discharging cycles; thereby, decreases the necessity for premature battery replacement which, in turn, contributes to the battery's life time. The goal of this research is to develop robust control technique to maximize the use of energy storage systems, renewable energy sources and the bidirectional power flow associated with EVs. The proposed robust control approach is based on combination of flatness theory with artificial neural network. The controller is responsible for maintaining the voltage DC bus stabilized and enhancing the quality of the power fed to the EV side. The performance of controlled EMS is verified via computer simulation within MATLAB/SIMULINK environment. As compared to classical proportional-integral (PI) control, the computer results show the proposed controller (FEMS-ANN) gives higher power quality of EV, lower overshot level in the DC voltage, faster response to abnormal conditions, and less steady state error.

用于电动汽车的强大能源管理系统

能源管理系统（EMS）对于电动汽车（EV）优化能源消耗、提高效率和增强车辆性能至关重要。EMS 可优化车辆各部件之间的能量分配，减少能量损失，最大限度地提高车辆效能。EMS 可减少电池压力，防止过度充电和放电循环；从而减少过早更换电池的必要性，进而延长电池的使用寿命。本研究的目标是开发稳健控制技术，最大限度地利用储能系统、可再生能源以及与电动汽车相关的双向电力流。所提出的稳健控制方法是基于平坦性理论与人工神经网络的结合。控制器负责保持直流母线电压稳定，并提高馈入电动汽车侧的电能质量。受控 EMS 的性能通过 MATLAB/SIMULINK 环境下的计算机仿真进行了验证。与传统的比例积分（PI）控制相比，计算机仿真结果表明，所提出的控制器（FEMS-ANN）可提高电动汽车的电能质量，降低直流电压的过冲水平，对异常情况做出更快的响应，并减少稳态误差。
