Dynamic Response of an Asymmetrical Spinning Space Station

The dynamic equations for a rigid asymmetrical spinning space station with an internal movable mass are presented in the appendix. The body rates induced by certain mass movements are shown to be elliptic functions for the uncontrolled space station. This assumes the mass movement is simulated by impulsive product of inertia changes. A linear analysis is presented for the controlled space station using a gyroscopic controller. The controller provides nutation damping and limited precession control.
