astronautics

Nevertheless , some manned flight mission requires the spacecraft has high pointing and stabilizing precision . so , it needs us to quantitatively analyze the astronautic disturbances , so as to evaluate flight mission and guide or improve spacecraft system design especially the attitude control system design 有的載人飛行任務需要航天器具有很高的指向精度和穩定度,這就需要對航天員的擾動進行定量分析,以便對飛行任務進行評估并能指導或改進航天器系統設計特別是姿態控制系統的設計。

The machine can be used in components of automobile and motorcycle , astronautic apparatuses , chips of integrate circuit electronics , packages of food , drink and cigarettes , keys of mobile phone , batteries , electric apparatuses , fittings and peripheral equipments of computer , ironware tools , stainless steel wares , electric products , communication products , medical devices , sanitation , cleaning and bathing wares , clocks and watches , jewelries , industrial bearings , electric wire and cable , garment . it can mark both words and graphs 廣泛應用于汽車、摩托車零部件、航天航空器件、集成電路芯片、食品飲料煙草包裝、手機按鍵、電池、電子元器件、電腦零配件及外設、五金工具、不銹鋼器具、電器產品、通訊產品、醫療器械、衛浴潔具、鐘表、首飾、工業軸承、電線電纜、服裝飾品等眾多領域的圖形和文字的標記

Research indicates that outer disturbances can be described with simple analysis and be estimated by outer atmosphere , and inner disturbances induced by the mechanical motion are also predictable and computable , but the inner disturbances induced by astronautic motion are stochastic and hard to predict 研究表明,外部擾動可以用簡單的分析來描述,并且可以通過外部環境參數來估計,內部機械運動引起的擾動也是可以預測和計算的。而內部由航天員活動引起的擾動,因其本身具有很大的隨機性而難以預計。

Based on chinese tracking and data relay satellite ( ctdrs ) in the future , the antenna pointing control and complex control theory of user satellite are studied deeply in this dissertation , which is funded by the improve item of dept . of astronautic engineering and mechanics ? “ the teaching demonstration of antenna pointing control system in tdrss ” . the main contents of this dissertation are consisted of the following parts : firstly , dynamics equation is derived using lagrange equation for user satellite , so as the kinetics equations of user satellite at the same time are expressed in the form with matrix differential equations that is suitable for attitude control system design and analysis 本學位論文結合航空宇航科學與技術學科研究生教學基地實驗室建設項目“中繼系統星間鏈路天線指向控制系統教學與演示實驗” ,以我國跟蹤與數據中繼衛星系統為背景,對某型號用戶星星間鏈路天線指向跟蹤控制和復合控制理論進行深入的研究,研究內容主要包括以下幾個方面: 1 .利用lagrange方程建立了用戶星的動力學方程,同時推導了運動學方程,并將這組動力學方程以矩陣微分方程形式表示,使之適用于姿態控制系統的設計和分析。
