Abstract

A robust adaptive controller is presented for the control system of user-satellite antenna acquisition and tracking TDRS (tracking and data relay satellite), which faces with the uncertainties of un-modeled dynamics and unknown bounded disturbance and the control input constraint. The stability is proved by using Lyapunov stabilization theory. The simulation results show that the robust adaptive controller can satisfy all the design requirements, especially the control accuracy is amazingly high with respect to the required accuracy. Also, the controller performs strongly robust for un-modeled dynamics and uncertainties of parameters.
