EN: Electromagnetic levitation of the vehicle is based on attractive forces generated between the electromagnets mounted on the vehicle and a ferromagnetic rail, laid along the whole length of the track. At that in each electromagnet the system of continuous current control is used. The guiding magnets, intended to stabilize the carriage motion in a horizontal plane, work on the same principle. In this paper the decoupling of equations describing the work of a horizontal stabilization system of the high-speed overland transportation on a magnetic levitation has been performed. The equations of vehicle motion include both mechanical joint variables and current magnitudes in the electromagnets, resulting in the need to analyze the systems of differential equations of higher order.
For equations decoupling the symmetry properties of the selected design model are used. Calculations are performed using the representation theory of finite groups. This allows finding of sets of new variables under which the equations shall be split into independent subsystems before equations composition. For the system under study we have found that the equations system of the 78th order is broken down into four subsystems having orders 12, 12, 28 and 26.
