Abstract :
This paper investigates the integrated attitude control algorithm and steering law for agile small satellites configured with control moment gyroscope (CMG). Firstly, considering the deterioration over time of the typical pyramid-shaped CMG cluster with 4 single-gimbal CMGs, build the CMG dynamic model. Then, based on the adaptive control theory to design the integrated attitude control algorithm and steering law, and prove the asymptotic stability of the closed-loop system via Lyapunov analysis. Finally, mathematical simulation has validated the solution in a satellite closed-loop attitude control system, and the simulation shows that the solution is simple and effective for attitude maneuver control of agile small satellites.
