给出了离散事件系统与模糊离散事件系统的模型及相关概念.利用模糊语言强截集这一概念,研究了分明语言的可控性与模糊语言可控性之间的关系,即在某种程度上两者是等价的.最后,从一个新的角度将离散事件系统的可控性特征推广到模糊离散事件系统的可控性.
The model and the related concepts of crisp and fuzzy discrete-event systems are formulated. The relationship of controllability between crisp and fuzzy languages, namely,they are equivalent to some extent, are studied by the concept of strong-cut language. Finally, some general controllability properties of crisp discrete-event systems are extended into fuzzy ones from the new point of view.
