The large-angle, nonlinear slew of the Spacecraft Control Laboratory Experiment (SCOLE) is treated with the assumption that the body is rigid. The optimal axis of rotation is first determined and then a time-optimal, bang-bang controller is designed. The controller is implemented in both open-loop and closed-loop form in a numerical simulation using DISCOS. Results are presented which demonstrate controller performance with respect to dynamic coupling compensation, size of the integration time step, and time delay in the response of sensors. The theoretical limit of expected performance is established, and provides a foundation is provided upon which a complete, flexible-body control methodology can be developed.
