Abstract:Base on the optimum method of controlling chaos dynamical
behaviors, by the feedback of transient small accessible parameter
perturbations in optimum control process, chaos in the unbalanced
flexible rotor system with the nonlinear unsteady-state oil-film force
is rapidly directed to a expectative orbit of an infinite number of
unstable periodic orbits which are embedded within the chaotic attractor
and stabilized, The numerical result shows that the chaos in the
dynamical film-flexible rotor system is also to be able to control
efficiently.
