The shaper affects both the roll and yaw inputs, and each individual input consists of two constant amplitude pulses. The cross-contribution of the roll and yaw inputs is considered in the formulation of the residual roll and yaw oscillation constraints. The resulting shaped roll and yaw inputs are then applied to several maneuver cases of a satellite with two symmetrical flexible solar panels. The simulation results show that the proposed constraint equations to limit the residual roll and yaw oscillations are valid and correct.
