This paper presents attitude trajectory control for a satellite system. The pitch loop of the satellite is controlled by momentum wheel; whereas the roll/yaw loops are stabilized by two different magnetic torques along their axes. The controller is on the basis of both the linear quadratic regulator (LQR) control theory and recursive least square (RLS) algorithm that is used to identify the equivalent linear canonical second order system for each axis at discrete points on references. Then, the… CONTINUE READING
