In this paper, the problem of large angle maneuver of spacecraft attitude is studied. The model of attitude kinetics which reaction wheels are as executive component of satellite attitude control system is considered. Based on the Lyapunov stability theory, controllers of the closed loop system are designed and the update law is obtained. Numerical simulation illustrates the feasibility of this technique. To demonstrate the robustness against the effectiveness of bounded noise of the proposed control strategy, the bounded noise is applied to the equations of kinetics and kinematics and perfect simulation results are obtained.
