Robust control of a spin-stabilized spacecraft via a 1DoF gimbaled-thruster and two reaction wheels.In impulsive orbital maneuvers, thrust vector misalignment from the center of mass (C.M) results in a large disturbance torque.  In this paper a thrusting maneuver system is proposed and studied which is based on the combination of a one degree of freedom (1DoF) gimbaled-thruster, two reaction wheels (RWs) and spin-stabilization.  The main goals are disturbance rejection and thrust vector stabilization without using reaction control systems (RCS).  The nonlinear two-body dynamics of the proposed system is formulated.  The controller design is formulated as a multi-objective optimization problem where the peak-value of the control input and H∞ performance are the cost functions.  Based on the peak-to-peak gain minimization, the accuracy of the linearized model can be guaranteed.  The optimization results give many optimal controllers which are acceptable for a thrusting maneuver.  The simulation results illustrate the applicability of the proposed method in presence of the sampling effects of the control inputs.
