Effects of Reaction-Wheel-Induced Disturbance on the Attitude of Three-Axis-Stabilized Geostationary Satellite;

The buckling behavior of reaction-wheel’s outer shell structure, composed of the base and the sealed cowling structure, is important in ensuring the reaction-wheel’s work environments.

Development of precise disturbance model of reaction wheel assembly on a spacecraft;

Micro-disturbance of reaction wheel assembly(RWA) is a key factor affecting the accuracy of spacecraft attitude control.

Reaction wheel is one of the main disturbance sources that affect the precision of attitude control system of spacecraft.

With the reaction wheel model and attitude sensor model being embedded in,the complete model of attitude control system is able to simulate the real Satellite Attitude Control System(SACS) at a component level.

Reaction wheel is one of the main disturbance sources for the attitude control system accuracy of spacecraft.

Through concrete examples, this paper expounds such physics properties as the inertial movement, reacting force and equilibrium in playing the piano and defines its scientific property.
