Research output: Contribution to journalConference articlepeer-review


Stability at critical load levels is analyzed using Hopf bifurcation theory. The authors consider the detailed two-axis model and show that a pair of complex eigenvalues associated with the excitation system undergo Hopf bifurcation near the critical load level. A center manifold is constructed, and the stability of the periodic solution so obtained is examined.
