Open publisher page 1 citations

Abstract

With the reaction wheel model and attitude sensor model being embedded in,the complete model of attitude control system is able to simulate the real Satellite Attitude Control System(SACS) at a component level.Quaternion feedback is employed for the control law design so that it enables the proposed controller to avoid singular position in numerical procedure.And the asymptotic stability was proved.As the real-time simulation experiments were made,it turned out that this simulation model can accurately perform as the SACS in real.
