摘要
分析了复合电源纯电动汽车的电源结构和工作模式,依据纯电动汽车基本性能指标对复合电源进行了能量匹配,制定了能源安全约束,并基于此制定了多目标模糊控制策略。仿真结果表明,所提出的控制策略能够充分发挥超级电容的优势,可提升纯电动汽车续驶里程、合理分配复合电源功率及减小车速误差。
In this paper, the structure and operating mode of battery/ultra-capacitor composite energy are analyzed,the parameter matching and security restraints are made according to the basic performance criteria of a BEV, and multiobjective fuzzy control strategy is established. Simulation results indicate that the presented control strategy can bring into full play the advantage of ultra-capacitor and expand the driving range of BEV, distribute reasonably battery/ultra-capacitor power and reduce vehicle speed errors.
