混合动力电动大客车模糊控制下的仿真分析

Simulation of control strategy for hybrid electric transit bus

针对不同道路循环工况,分析驾驶员控制过程,提出了一种模糊逻辑控制策略。应用仿真软件ADVISOR建立控制策略模型,通过多种道路循环和不同的控制策略进行仿真分析。结果表明,该模糊逻辑控制策略有较好的鲁棒性,能合理分配发动机和电动机的转矩,保证了混合动力客车优良的燃油经济性和排放性。

Aiming at different driving cycles and analyzing driver＇s control process, a fuzzy logic control strategy was preented. The model of control strategy was based on ADVISOR and simulated under several driving cycles and different control strategies. The results showed that the fuzzy logic control had good robustness and could distribute the torque between the engine and motor reasonably, and the optimal control of the entire vehicle was ensured.
