The direct adaptive fuzzy robust control for satellite attitude control

In this paper, the direct adaptive fuzzy robust control is applied to the attitude stabilization control of the satellite, and the detailed design procedure of the fuzzy control system is presented. The controller directly acting on the controlled system doesn´t require the modeling of the uncertain nonlinear system. The direct adaptive fuzzy controller is designed for the satellite, and the robust control term is added to the system in order to resist the external disturbances. The adaptive law of the rule parameter is derived. Simulation results show that precise attitude control is accomplished in spite of the uncertainty in the system.
