摘　　要：介绍了磁流变液风扇离合器的工作原理和测控系统的设计。提出了大偏差饱和分段控制及小偏差模糊控制的组合控制策略,给出了模糊控制器的详细设计。结果表明,该系统不仅可以提高冷却水温度的控制精度,提高发动机输出效率,也实现了节能。The fundamental principle of MR fluid fan clutch is introduced and a measurement and control system is designed. A composite controlling strategy, which adopts saturated subsection control for big error and fuzzy control for small one, is put forward. Detailed design of fuzzy control implement is presented. Results prove that control precision of temperature for cooling water and output efficiency of engine are improved, and energy is also saved.
