Adaptive variable structure control of fast maneuver of attitude for the complex flexible satellite

For the three-axis stabilized complex satellite with large flexible solar panel and satellite antennae, a fast maneuver of attitude and stability controller was designed, which combined the multivariable adaptive control method based on the characteristic model and variable structure control. The global reaching conditions of the sliding mode and the stability of the closed loop system are shown through Lyapunov stability theory. A numerical simulation was presented. The simulation results show that the designed control method can insure the fast maneuver and stability performance.
