Abstract :
A state feedback ℋ∞-suboptimal control problem on TSO(3) for a rigid spacecraft with three control torques and disturbances is addressed, the Hamilton-Jacobi inequality associated with a corresponding state feedback ℋ∞-suboptimal control problem on TS3 is solved globally. The ℋ∞-suboptimal state feedback on TS3 involves the Euler parameters and solves the original problem on TSO(3) when the initial values of the Euler parameters are appropriately chosen
