发动机电液混合驱动冷却系统模糊控制器的仿真分析

摘要

In order to control the cooling liquid accurately, a fuzzy method for controlling the engine coolant temperature was proposed. The working process in the electro-hydraulic mix-drive cooling system was also analyzed. The main data in this system was analyzed too. In addition, the important data were matched in this system. The fuzzy controlling method was proposed for engine’s coolant temperature. If a little improvement of this engine cooling system was made, the problem that the cooling liquid temperature is difficult to be controlled accurately was solved.%为了达到较准确地控制冷却液温度的目的，采用模糊控制方式对发动机冷却系统进行控制。分析了发动机电液混合驱动冷却系统的工作过程，对系统主要参数进行了匹配，提出了发动机冷却液温度的模糊控制方法，实现了稍微改进发动机冷却系统，解决了发动机的冷却液温度难于准确控制的问题。
