Nonlinear adaptive attitude control of satellite using gyrotorquers
A nonlinear adaptive control law for the attitude control of satellites using gyrotorquers is presented. The derivation of the control law does not require any information on the system dynamics and the environmental disturbance torques acting on the satellite. A simplified control law for spinning satellites is derived. The controller requires only attitude tracking error and its derivative for feedback. Simulation results are presented which show that, in the closed-loop system, precise attitude control can be accomplished in spite of the uncertainty in the system
