【摘要】 提出了发动机冷却液温度的模糊控制方法,将冷却液温度进行模糊化,根据实验建立了相应的模糊控制规则库;应用MATLAB软件的模糊逻辑工具,计算分析得到了控制查询表,建立了以Motorola单片机MC68HC908LJ12为核心的硬件系统,并对软件进行了设计。试验表明,该方法只需对现有的发动机冷却系统进行较少的改进,便可较好地解决发动机的冷却液温度难于准确控制的问题。更多还原

【Abstract】 A fuzzy method for controlling the engine coolant temperature is prposed.The fuzzy rule base is correspondingly established based on the experimental data.The control query table is created through computing and analyzing via the fuzzy logic tools in MATLAB.The hardware system,centering on MC68HC908LJ12,is conducted.The software is designed as well.The test indicates that only a little improvement of the current engine cooling system can better solve the problem that it is difficult to accurately control the engine coolant temperature.更多还原
