| 摘 要： | 云模型是对语言值所蕴含的模糊性和随机性的一种数学描述,它用期望值Ex,熵En和超熵He表征定性概念,将概念的模糊性和随机性集成在一起,是实现知识库中定量与定性之间相互转换的一种新途径.本文论述了模糊子集的云模型表示、基于云模型控制规则的不确定性推理,并设计了船舶航向保持系统的一维与二维云模型控制器.仿真结果表明,该控制器简易、直观、鲁棒性强,具有良好的控制性能和较好的应用价值.

| Abstract: | The cloud model is a mathematical representation to fuzziness and randomness in linguistic concepts.It represents a qualitative concept with expected value Ex,entropy En and hyper entropy He,and integrates the fuzziness and randomness of a linguistic concept in a unified way.This model is a new method for transformation between qualitative and quantitative in the knowledge.This paper presents the cloud model of fuzzy sets,uncertainty reasoning of control rules based on cloud model,and one-dimension and two-... |
