摘要
以某5t并联式混合动力装载机为研究对象,通过载荷谱分析了其工况特点,提出模糊逻辑控制策略,通过在线估计系统需求转矩,以需求转矩和超级电容SOC值作为输入,得到发动机和电机输出转矩。结果表明:本文控制策略改善了发动机燃油经济性,比传统装载机节油约7.8%,实现了节能效果。
It takes the loader of parallel hybrid power as the object to study the control strategy. Through analyzing the working character of a five-ton loader＇s load spectrum, the control method of fuzzy logic was put forward. Take the required torque of system which was estimated online and super capacitor＇s SOC as the input to get output torque of engine and electromotor. The result shows that the control strategy raises the fuel economy of the engine. Comparing with traditional loader, it can save about 7.8% fuel and achieve the goal of energy-saving.
