The Combined Control Algorithm for Magnetorquer and Reaction Wheel of Small Satellite
|
Abstract:
Magnetorquers and reaction wheels are the important control actuators of the modern small satellite. Because it uses the magnetorquer as the actuator, the dynamic system of the small satellite is a nonlinear system with the restrictive conditions. Aimed at the initial attitude capture, a combined control algorithm for the magnetorquer and reaction wheel has been adopted. The simulation results indicated that the algorithm has excellent robustness and can be designed and realized easily. The algorithm has reduced the saturation opportunity more obviously than using the reaction wheel only, and increased the attitude convergence speed more greatly than using the magnetorquer only
