摘要

通过对某五吨装载机工况特点的分析，提出了一种并联混合装载机结构，对其参数匹配进行了研究，并提出了一种节能模糊逻辑控制策略。模糊控制器的输入变量为在线估计得到的系统需求转矩和超级电容的充电状态。通过模糊控制优化算法，使发动机在高效率区平稳工作，使超级电容器保持充放电平衡。仿真结果表明，该控制策略提高了发动机的燃油经济性和节能效果，与传统装载机相比，可节省7.72%的燃油。

Research on control strategy for parallel hybrid loader

Through the analysis of a five-ton loader working condition characteristics, this paper proposed a parallel hybrid loader structure, studied its parameter matching and put forward a fuzzy logic control strategy for energy saving. The input variables of fuzzy logic controller were system demand torque obtained by online estimation and state of charge of super capacitor. After fuzzy control optimization algorithm, the engine would work smoothly in the high efficiency area and super capacitor would keep balance between charging and discharging. The simulation results showed that the control strategy improved the engine fuel economy and energy saving effect which could save fuel by 7.72% compared with the traditional loader.
