中文摘要 |
Pawlak提出的粗糙集理论是一种刻划不确定性的数学工具. 本文研究了基于粗糙集理论建立模糊模型的方法,提出了扩充与整定的概念,并运用所提出的方法建立了脉冲TIG焊动态过程模型. 经模型有效性确认表明该方法是有效的. |
英文摘要 |
The rough set theory, which is proposed by Pawlak, provides a tool for describing uncertainty. This paper discusses the method of building fuzzy model based on the rough set theory, presents concepts of adjustment and expansion, and the dynamic model of pulse TIGwelding process is built by the proposed method. The validations of models are done and the results show that the method is effective. |
