Abstract
A possibility of using the feedback control for changing conditions of the noise-induced transition in a nonlinear second order dynamical system is studied. The control function is constructed using the speed-gradient method for a linearized model system. It is found by the computer simulation that the efficiency of control depends on its intensity in a nonmonotonical way, its characteristics having a resonance-like shape.
