Study and Simulation on Adaptive Fuzzy Control Method for Automotive Engine Speed

在深入分析常规模糊控制中量化因子和比例因子对系统响应影响的基础上,设计了一种参数自调节的自适应模糊控方法.根据转速响应的不同阶段,对输入量化因子和输出比例因子进行自适应调节,改善系统的动态性能.通过与常规模糊控制方法的仿真比较,参数自调节的自适应模糊控制方法具有明显的优势.

This paper thoroughly analysed the effect of proportion factor and quantification factor on system response in general fuzzy control method. On this basis, a fuzzy adaptive control method with parameters self-adjusting on line was designed. According to different phases of the speed response, adjust output proportion factor and input quantification factor adaptively, to improve the dynamic performance. This method has obvious advantage comparing with the general one.
