We consider a generalization of Whitney's problem of periodic motion of an inverted spherical pendulum in the presence of a horizontal periodic force, in addition assuming that velocity-dependent forces act on the pendulum. A method of the introduction of additional dissipative forces is presented. This method allows us to prove the existence of forced oscillations in the considered problem.
Keywords: forced oscillations, Whitney pendulum, stability, periodic solution
Mots-clés : Lorentz force, friction.
