Attitude Control Of Intra-Satellite With Unknown Time-Delay

Aiming at the intra-satellite communications time delay problem of the control system in wireless small satellites, and considering that the satellite's angular velocity can't be measured in some cases, a time delay state feedback controller based on MRPs model is designed. In this controller, angular velocity information is not needed. And the asymptotic stability of the control system is proven by the Lyapunov-Krasovskii stability theory. Simulation results illustrate that the attitude of satellite can be stable with the proposed controller.
