同時,針對mems的系統級模型是一個混合信號模型,具有多能量域耦合、多信號混合、離散事件子系統與連續時間子系統交互的特點,使用vhdl - ams作為混合信號模型建模的工具,採用多埠組件網路建模方法建立了mems系統級模型,把微型機電系統分解為多個子系統或組件,各子系統被定義為多埠組件,子系統的內部行為通過其埠行為來描述,子系統間的能量與信號的交換通過組件的埠映射來實現,從而實現了對連續時間系統和離散事件系統的建模與模擬,滿足了非線性系統以及大信號分析要求。Through the model the inverse dynamic problem of stewart platform is solved and a foundation is made for stewart platform control used for 500m lt. meanwhile all the restrained forces acted at joints are found which provide analysis condition for the mechanism design. a simplified resultant force acted on the cabin by stewart platform is given which makes it possible to eliminate the dynamic coupling between the two subsystems by means of active vibration control
基於newton - euler方法,建立了充分考慮動平臺慣性、支腿慣性、關節摩擦等因素的stewart平臺控制動力學模型,解決了已知動平臺運動規劃,求關節驅動力的動力學逆問題,為準確實現lt500m原型stewart平臺控制奠定了基礎;解出了各關節處的約束反力,為平臺機構設計提供了力分析條件;簡化給出了平臺對饋源艙的反作用力,使得採用振動主動控制技術消除兩級子系統之間的動力耦合成為可能。Due to a & b double flats setting of stp ( signalling transfer point ) in different place, and working on mode of payload - sharing on signalling links ( couple links ) between sp ( signalling point ) and stp, the calling signalling sequence cannot be collected completely from single stp. thus it is difficult to synthesize signalling affair in the signalling supervision system. the first, this thesis illuminateds network architecture of no. 7 signalling network and no. 7 signalling centralized supervision system
由於七號信令網的信令轉接點設備stp ( signallingtransferpoint )採用a 、 b雙平面異地設置,下一級的信令點設備sp ( signallingpoint )至上一級的一對stp之間的信令路由採用負荷分擔方式工作, sp至stp對的負荷分擔鏈路形成耦合鏈路,導致在一個stp處無法採集到完整的呼叫信令序列,這樣就給監測系統核心部分之一的信令事件合成帶來了極大的難度。Traditional eai technology is confined to software development mode and system integration methods, which lead to compact coupling among enterprise application systems, and blocks enterprise " s system upgrade and development
