Optimal Stabilization of the Earth Artificial Satellite with Redundant Fly-Wheels under Uncertain Conditions
要約
Consideration is given to the observation problem of the state vector errors of SC in its spherical motion in the stationary circular orbit using the information of three-component magnetometer (the navigation task of determining the satellite position is assumed to be solved beyond the scope of this work). The application of the rigid synthesis method of nonlinear stabilization systems ensures the uniform asymptotic stability of homogeneous error observation system and the stable observer construction under uncertain conditions. Therewith the quality of satellite stabilization in the orientation mode is on average by 28% (by results of mathematical simulation) worse than that of its stabilization with the controller using precise values of its angular velocity deviations from the nominal values.
