| 摘 要： | 从优化模糊控制器的角度出发，讨论了变论域思想和伸缩因子的概念，同时就量化、比例因子和伸缩因子的关系进行了分析，进而阐述了一般情况下两种伸缩因子的选取方法；在此基础上将模糊PID和变论域思想想结合，形成变论域自适应模糊PID控制结构；最后通过某复杂非线性系统进行仿真研究，结果表明该方法达到了预期目的，优越性明显。

| Abstract: | From the point of view of the optimization in fuzzy control, the idea of variable domain and the concept of flex factor are discussed. At the same time the preponderance of variable domain and the relationship between the quantization factor, the proportional factor and the flex factor are explained. In addition, the method of selecting the two flex factors is analyzed in detail. Another new intelligence control means - fuzzy logic adjusting PID online based on variable domain on self- adaptation is realized by putting the idea of variable domain into fuzzy PID. The research is based on some complicated nonlinear system, and the result of simulation is predominant. |
