| 英文摘要 |
| A distributed cooperative super-twisting sliding mode controller based on disturbance observer is designed
for multi-spacecraft attitude cooperative control problem affected by external disturbances and actuator faults. Firstly, the
external disturbances and actuator faults of each spacecraft are regarded as a lumped disturbance, and adaptive sliding
mode disturbance observer is designed to estimate the disturbance. A distributed cooperative controller based on attitude
consensus error of multi-spacecraft is designed by combining super-twisting algorithm with integral sliding mode surface.
It is proved by Lyapunov stability theory that the designed attitude of multi-spacecraft can converge to the neighborhood
near the equilibrium point in finite time. Finally, simulation and comparison results show that the designed controller can
accelerate the convergence speed of the system and improve the control accuracy of the system. |
