傳統的經典動力學研究對象是一種被動結構, 在被動結構中引入控制器件或機敏元件后, 被動結構變成主動結構。但在原結構上附加的傳感器和作動器, 使得結構過于龐大和復雜; 同時, 主動結構為非自伴隨結構, 導致結構和系統的可靠性低。虛擬傳感器和融合理論的應用, 將在很大程度上解決這個問題。本文介紹了虛擬傳感器的基本概念和應用模型, 給出了虛擬傳感器的計算方法; 介紹了融合理論、融合結構和融合算法; 列舉了虛擬傳感器及融合的應用, 并提出將虛擬傳感器和融合理論應用于主動結構的設想。

Abstract: T radit ionally, the object ive of the classical dynam ics are passive st ructures. They w ill become act ive st ruc2 tures w hen same cont ro llers and smart components are added to them. How ever, the p rimary st ructures w ill be2 come too bulky and comp lex due to the addit ional senso rs and actuato rs. In addit ion, act ive st ructures have non2self2
adjo int characterist ic w h ich lead to reduct ion of the reliability of the system s o r st ructures. In th is paper, virtual senso r and data fusion are int roduced to so lve the p roblem. Basic idea and models fo r app licat ions of virtual senso r are p resented. The algo rithm of virtual senso r is p resented. The theo ry of fusion is int roduced, asw ell as fusion con2
st ruct ion and its algo rithm. The app licat ions of virtual senso rs and data fusion are illust rated. F inally, the perspec2 t ive of the app licat ion of virtual senso r and data fusion in act ive st ructures is p resented.
