A satellite dynamicis equivalent concept is introduced in this paper. Concepts and methods of the dynamic analysis and control for the spin-satellite are extended to the dualspin satellite. A design method of the double-pulses closed loop control for the dual-spin satellite is presented, the wobbling of the satellite caused by the structure error is analysed. The formulas for computing the wobbling angle and the stability criterion are also given. It has been proved that a ball-in tube nutation damper...

A satellite dynamicis equivalent concept is introduced in this paper. Concepts and methods of the dynamic analysis and control for the spin-satellite are extended to the dualspin satellite. A design method of the double-pulses closed loop control for the dual-spin satellite is presented, the wobbling of the satellite caused by the structure error is analysed. The formulas for computing the wobbling angle and the stability criterion are also given. It has been proved that a ball-in tube nutation damper can be used in the dual-spin satellite and that the wobbling giving some significant effect on the attitude ereor can not be damped out by the ball-in tube nutation damper. The maximal attitude angle error of the satellite is equal to the sum of nutation angle and wobbling angle. Finally, the analytical results are checked by simulation testing.

本文引入卫星动力学等效概念,把单自旋卫星的动力学分析、制控的概念和方法推广应用到双自旋卫星。提出了双自旋卫星的双脉冲闭路控制的设计方案。分析了由于结构误差引起的摆动,给出了摆动角的计算公式和卫星姿态的稳定判据。论证了管一球武章动阻尼器也适用于双自旋卫星。证明了章动阻尼器不能消除摆动,甚至对卫星姿态误差产生不可忽视的影响;最大姿态误差角等于章动角和摆动角之和。最后,用仿真试验验证了分析结果。

Abstruct Data Type is a powerful tool for implementing object—oriented pro- gramming.The goal of this paper is to specify abstract data type and provide its mathemati- cal meaning by using algebra structure;meanwhile,point out that any abstract data type of visible symbol Σ is the class of homogeneons structure of a Σ-computing structure.Furth- more,get a chain of results that abstract data type is equivalent to related computing struc- ture,based on equivalent concept of the basic item T (Σ).

抽象数据类型是实现面向对象程序设计方法的有力工具.本文的目的在于利用抽象代数结构来描述抽象数据类型并给出它的数学含义;同时,指出任意可见标志Σ的一个抽象数据类型是一个Σ一计算结构的同构类,从而在基本项 T(Σ)上的等价概念基础上,得出了抽象数据类型与有关计算结构等价的一系列结论.

The authors prove that: the confortnal operator.the similitude operator, the first and second orthogonality preserving operators.and the ortho-invariant operator are five equivalent concepts,and in such case, T ‖T‖ is always a unitary operator.
