چكيده لاتين :
in this study, we designed a fault tolerant controller
for satellite attitude determination control system (ADCS) by
combination an adaptive-sliding mode controller and gyro bias
estimator. The observer estimates quaternion and bias error and
then by using satellite kinematics equation, produces real velocity
of satellite. The proposed method could tolerate disturbances in
space and also dynamic uncertainty up to 30% and omit gyro
bias error completely. Stability of combined controller and
observer proved by Lyapunov stability.
