Abstract :
In view of the small satellite attitude system where no gyro is available or gyro fails, the quaternion estimating angle rate of satellite is proposed by means of sliding mode observer. Based on the attitude rate estimator, the decoupling variable structure controller is designed for attitude control system. The simulation results show that the accuracy of estimating is rather high, and the variable structure control method has advantages of being easily designed and realized.
