Adaptive control for a satellite attitude tracking system

This paper deals with the problem of attitude tracking control of rigid satellite subject to external disturbance, and parametric uncertainty. An adaptive controller is designed to implement real-time identification for inertia parameters and control parameter is adjusted dynamically. A detail stability analysis of the close loop system is included and system is finite-gain L₂ stable. Simulations are performed for the satellite attitude control system. Simulation results demonstrate that the control scheme realizes the attitude tracking control and implements identification for inertia matrix and effective rejection for disturbances.
