In this specific example the underlying problem arises in computing the steady spins of a heavy asymmetric rigid-body about a fixed point (the so-called Axes of Staude).
The two parameters are actually Lagrange multipliers associated
with two constraints, the problem has a Lagrangian and a Hamiltonian, and
the stability of solutions is a well-defined concept.
