The problem of designing discrete-time attitude controllers for three-axis stabilization of magnetically actuated spacecraft is considered. Several methods are discussed and an approach to the tuning of various classes of projection-based controllers is proposed relying on periodic optimal output feedback control techniques. The main advantages of the proposed methods are discussed and illustrated in a simulation study.
