Sliding Mode Controller for Satellite Attitude Stabilization Maneuver

摘要

Attitude control system of the rigid satellite is a coupling and uncertain nonlinear system with multi-inputs and multi-outputs. This paper presents a sliding mode controller for the satellite attitude system with limited control input and external disturbances. The design strategy can guarantees that the closed-system is global asymptotic stable and realizes the requirements of the control input saturation. The control algorithm is model-independent and it performs effectively on restraining bounded external disturbances.
