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(xué)位論文結(jié)合航空宇航科學(xué)與技術(shù)學(xué)科研究生教學(xué)基地實(shí)驗(yàn)室建設(shè)項(xiàng)目“中繼系統(tǒng)星間鏈路天線指向控制系統(tǒng)教學(xué)與演示實(shí)驗(yàn)” ,以我國跟蹤與數(shù)據(jù)中繼衛(wèi)星系統(tǒng)為背景,對某型號用戶星星間鏈路天線指向跟蹤控制和復(fù)合控制理論進(jìn)行深入的研究,研究內(nèi)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(xué)方程,同時推導(dǎo)了運(yùn)動學(xué)方程,并將這組動力學(xué)方程以矩陣微分方程形式表示,使之適用于姿態(tài)控制系統(tǒng)的設(shè)計(jì)和分析。
百科解釋
A differential equation is a mathematical equation for an unknown function of one or several variables that relates the values of the function itself and of its derivatives of various orders. A matrix differential equation contains more than one function stacked into vector form with a matrix relating the functions to their derivatives.
