Abstarct: This thesis presents the development of a robust adaptive fuzzy controller utilizing output feedback for state tracking of a rigid satellite, even in the presence of unknown inertia, unknown dynamics, and external disturbances. Due to the limited availability of measurable information, a viewer is employed to estimate the angular velocity of the system. The satellite system is modeled using the modified Rodrigues parameters model. Nonlinear functions of the system are approximated using fuzzy inference systems, enabling the desired system's stability to be ensured through the utilization of Lyapunov's stability theory. The effectiveness of the proposed controller is demonstrated through simulation experiments.
