In this paper a method is presented, in which the rotation angle from sun-earth midsean λ_(se) in addition to the earth angle θ_e and sun angle θ_s are simultaneously used for determinating spinstabilized geostationary satellite attitude. This method gives uniquely one unambiguous attitude.

In this paper a method is presented, in which the rotation angle from sun-earth midsean λ_(se) in addition to the earth angle θ_e and sun angle θ_s are simultaneously used for determinating spinstabilized geostationary satellite attitude. This method gives uniquely one unambiguous attitude. Solution, simplifies the algorithm, eliminates regions of high correlation and low measurement density occuring when using two attitude measurements, and provides geometric condition where singularity occures only if the earth and sun vectors are co-linear. By this method, the angle λ_(se) is conveniently incorporated into the kalman or least square filter. Digital simulation showed that better accuracy of attitude determination and filter estimation can be obtained bv this method.

本文提出一种同时利用地球角θ_c、太阳角θ_s和星日-星地转动角λ_(sc)三种姿态测量信息,确定卫星姿态的方法。该法算式简易,可唯一地确定卫星姿态。消除了采用两种姿态测量信息的姿态确定方法所引起的高相关和低测量密度的不良区域。本文方法仅有太阳矢量和地球矢量共线的几何限制,能方便地把λ_(sc)引入滤波器。通过数字仿真,表明此法可得到良好的姿态确定精度及滤波估计。

In this paper a nonlinear selfajusting digital filter and a linear nonrecoursive digital filter are investigated on the basis of the early papers [1] and [2]. Both of these filters can be served as compensators of attitude control of flexible vehicles. The algorithm for the nonlinear selfajusting digital filter has been simplified and improved in comparison with that in [1]. Besides the selfajusting characteristic has been redesigned for a flexible vehicle. In this paper the algorithm as well as the estimation of the computing operations is given. What is more, the results of a digital simulation show that the control effect of the above-mentioned filters is very good.

本文在以前结果[1]、[2]的基础上,对非线性自整定与线性非递归式两种数字滤波器作为弹性飞行器姿态控制校正装置进行了研究。非线性自整定数字滤波器的算法相对于[1]做了简化和改进,其自整定特性针对弹性控制对象进行了重新设计。文中给出了算法,运算量估计及作为设计例的某飞行器姿态控制系统动态过程的数字计算结果。设计例验证了两种滤波器的设计、算法和控制效果。所提出的两种数字式控制方案,在实现时作为控制元件仅需求一台微型数字机,而无需速率陀螺。

An example of an attitude control system of a bending vehicle is given. To show the merit of the new digital filter, the realization of the proposed digital...
