In Kleppner & Kolenkow's Introduction to Mechanics (Amazon link), the general gyroscope motion including nutation was derived using the approximation condition $\Omega T \ll 1$ where $\Omega$ is the precession angular velocity and $T$ is the period of nutation.
How does one describe the gyroscopic motion if the the condition for the approximation is not satisfied? How does one describe the general gyroscopic motion if
- the angular momentum of precession is not negligible and
- if the gyroscope spins very slowly around its axis, $\omega$ is low?
In general I want to find the formula for most general gyroscope motion. If I let $\omega$ go to zero then I should get the special case of a pendulum.
