Abstract :
This paper presents a state feedback H∞ sub-optimal controller for satellite attitude system with three control torques and disturbances. A global solution to the associated Hamilton-Jacobi-Issac (HJI) equation is found. The stability properties of the closed loop system are studied and simulation results are presented to evaluate the performance of the proposed control strategy.
