摘要

Distributed (field) feedback control for instability suppression of oscillations of elastic plate, streamlined top by electricity conductive magnetohydrodynamical flow and bounded below by non-conductive medium is considered. The system is under constant non-perturbed magnetic field. Control as a means of active variation of the object properties is realized by means of perturbed magnetic field, which holds the same equations as controlled object. Increase of feedback factor enhances system stability, therefore the Mach critical number Mcr increases considerably.
