Abstract


This paper presents a new algorithm in adaptive robust control of satellite with parametric uncertainty as inertia components. The algorithm can be described as a combination between fuzzy logic controller and robust sliding mode controller. Adaptive fuzzy of robust sliding mode controller (AFRSMC) as an intelligent robust nonlinear control algorithm, is designed to control satellite attitude system with complicated structure of nonlinearity, actuator saturation and unknown parameters. This algorithm is generic for attitude control system whatever the parameters of the satellite. It generates a relation between states measurements and controller gains. This relation enables the controller to govern attitude system even for unknown inertia components or disturbances models without high deterioration in performance of the system.The performance of the control algorithm is measured by study of sensitivity analysis.
