% Demonstrate controlling nutation and the momentum axis of a spacecraft The spacecraft is a gyrostat. The controller uses a single pulse to damp nutation. This demonstrates how to do manual nutation and momentum axis control. The system is designed to kill nutation with one pulse so that the roll angle is zeroed at the same time. This also shows an analytical computation of nutation frequency and compares it with eigenvalues from the Jacobian of the nonlinear equations. ------------------------------------------------------------------------ See also: RHSGyrostat, NutationMWA, Jacobian, DispWithTitle, RK4, QTForm, TimeLabl, Plot2D ------------------------------------------------------------------------
