并联混合动力汽车模糊逻辑控制策略的设计

Design of Fuzzy Logic Control Strategy of the Parallel Hybrid Electric Vehicle

利用模糊逻辑控制技术,设计了并联混合动力汽车的模糊逻辑扭矩控制策略。选取了控制器的输入、输出变量,构建了有25条规则的模糊推理器。在3种不同的循环工况下,分别对二值逻辑策略和模糊逻辑策略进行了仿真试验,结果显示,所设计的模糊逻辑控制策略能够很好地控制发动机工作,且具有很好的自适应能力和鲁棒性。

Applying fuzzy logic control technology to design fuzzy logic torque control strategy of the parallel hybrid electric vehicle.The input and output variables of control unit are selected and a fuzzy inference unit with 25 rules is constructed.We simulate the two-valued logic and fuzzy logic control strategy respectively under three different kinds of circulation working condition,the results show that the fuzzy logic control strategy can control the engine work effectively and has powerful adaptive ability and robustness.
