摘要
针对电动汽车行驶工况及驾驶员操作具有一定非线性和时变不确定性的问题,对整车控制器的控制算法和电池管理系统进行了研究,提出了一种驱动转矩分配的双模糊控制策略。对纯电动汽车建立整车动力学模型和驾驶员输入参数模型,以基本转矩模糊控制器和补偿转矩模糊控制器来求解,并优化驱动转矩值,采用CAN总线通讯经过电机驱动器来控制驱动电机的转矩输出。以CYC_HWFET高速工况和CYC_EUDC中低速工况为例,基于ADVISOR平台对双模糊控制器的电动汽车进行性能仿真分析。结果表明,所设计的双模糊控制器在满足纯电动汽车动力性要求的同时,也能获得较优的经济性且动力电池利用效率较高。
In response to the problems that the driving conditions of electric vehicle and the driver s operation have certain nonlinearity and time -varying uncertainty,the control algorithm and battery management system of the vehicle controller were studied,proposing the double fuzzy control strategies distributed by driving torque. Firstly,the vehicle dynamics model and the driver input parameters model were established for the electric vehicle,seeking the solution of the torque values and optimizing the driving torque values by virtue of the basic torque fuzzy controller and the compensation torque fuzzy controller so that the CAN bus could communicate with the motor driver to control the torque output of the driving motor. The ADVISOR platform was applied to conduct performance simulation and analysis of electric vehicles with double fuzzy controllers . The simulation results show that by exemplifying the CYC_HWFET high-speed working condition and the CYC_EUDC medium & low-speed working conditions,the electric vehicle with double fuzzy controllers designed meets the power requirement and can attain better economy and higher power battery utilization efficiency.
