Abstract EN
This paper presents a new robust inverse optimal control strategy for flexible spacecraft attitude maneuvers in the presence of external disturbances and actuator constraint.
A new constrained attitude controller for flexible spacecraft is designed based on the Sontag-type formula and a control Lyapunov function.
This control law optimizes a meaningful cost functional and the stability of the resulting closed-loop system is ensured by the Lyapunov framework.
A sliding mode disturbance observer is used to compensate unknown bounded external disturbances.
The ultimate boundedness of estimation error dynamics is guaranteed via a rigorous Lyapunov analysis.
Simulation results are provided to demonstrate the performance of the proposed control law.
