Finite Time Fault Tolerant Attitude Control-Based Observer for a Rigid Satellite Subject to Thruster Faults

A rigid satellite fault diagnosis strategy, subject to faults of external disturbances and thruster faults, is developed. In this design, an equivalent idea is introduced to design a sliding mode observer that can detect and identify the failures indicated previously. Considering the measurability of parameters of the satellite, such as angular velocity and attitude, a sliding mode observer is implemented. Next, the amplitudes of the faults and...
