| Considering the features of a low-inclination measuring satellite, this paper presents a composition conception for the attitude control system of the low-inclination measuring satellite.Several models are established in this paper, such as the model of attitude kinematics and dynamics, the model for measuring star sensors, gyros, and infrared horizons, a flywheel model, and a mathematical model of disturbance torque. Besides, it gives the principle and conception of pole assignment.Effective control model and mathematical model have been set up to meet mission requirement by the combination of some attitude-control means like analysis, calculation and simulation. It will become a valuable reference for the subsequent follow-on satellite versions. |
