Abstract: 

In general, most of satellites have nonlinear dynamic together with uncertainty and restricted constraints on their actuators. In this paper, stability of satellite by using sliding control as a robust control is proved in such a way that influences of above-mentioned limitations has been reduced. In this regard, after deriving dynamic and kinematic equation based on quaternion, sliding surface will be designed such that it will be stable. It is then illustrated that discrete sliding control law will not guarantee stability, but continuous one will guarantee satellite stability by proving. Finally, fine performance of designed control law is shown by simulation on a spinning satellite considering practical aspects.
