模糊滑動模式於相鄰結構之控制

A Study on Structure Control of Adjacent Structures by Fuzzy Sliding Mode

指導教授 : ARRAY(0xc4b624c)

摘要


有別於傳統的結構形式,本文在各自獨立的相鄰結構間以致動器(actuator)連接,使之成為平行結構系統,再以廣義的單棟結構形式重新建立結構模型,並使用模糊滑動模式(fuzzy sliding mode control, FSMC)進行結構主動控制。 鑑於平行結構系統複雜的運動行為,本研究利用模態分析(mode analysis)、頻率軌跡轉向(frequency loci veering)分析與強制振動(forced vibration)等三個方法進行研究。模態分析與頻率軌跡轉向分析之目的為探討平行結構系統在不同結構參數下之動力特性。而強制振動則可對上述兩種分析結果進行驗證,並比較不同類型的平行結構系統,在被動控制及模糊滑動模式主動控制下,其動態反應之差異性。

並列摘要


The objective of this study is to detailedly investigate the dynamic characteristics of parallel structures. A mathematical model of parallel structures connected with an actuator for structural motion control is developed. The fuzzy sliding mode control (FSMC) strategy is presented to reduce structural response under seismic excitation. On the basis of a computational procedure, modal analysis, analysis of frequency loci veering and forced vibration analysis are conducted to assess the effectiveness of the proposed algorithm. The results indicate that the control effectiveness is greatly influenced by both relative motions of parallel structures and coupled effects.
