This report presents approximate analysis and synthesis methods of a digital attitude control system of an aerospace vehicle in the P-domain and S-domain. By means of the methods, it is very convenient to design a control system, particularly when it includes a nonlinear element and when it has to adopt the measured data of frequency response for some physical components, In the report we came to a conclusion that a digital compensation system can yield the same steady performance as an analogous one. Finally,...

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.
