Attitude Stability of Satellite using Lyapunov equation

For that the attitude control performance test of the satellite, dynamic analysis of satellite structure performed in reference with KOREASAT, and the equation of motion of rigid bodies was derivated. For attitude stability, Lyapunov's stability theorem and state space expression were applied to dynamic equation of satellite. To prove efficiency of our method, simulations are performed and result are shown.
