Finite Time Sliding Mode Controller for a rigid Satellite in Presence of Actuator Failure

satellite attitude control,finite time sliding mode control

Attitude control executes an important role in satellite performance and is one of most critical implement in development of spacecraft technology. According to the presence of several uncertainties and disturbances in complicated satellite system in harsh space environment, taking advantage of developed anti-disturbance control methods is beneficial. This paper presents some nonlinear sliding mode control scheme for a satellite with various reaction wheel faults as uncertain parameters. Attitude quaternion and its derivative commands are robustly tracked via sliding mode controllers to become inclined to zero.
