Part of a maglev train’s partial motiones are parasitic - not useful, or malicious to the successful solution of it’s motor task. Under the conditions of unpredictable system’s disturbances, the requirement to preserve it’s purposefulness makes it rational the passive suppression of such motiones by the methods of the invariance theory. These methods are used to find conditions, the observance of which guarantees the independence of a suppressed coordinates from certain perturbations. Suppression can be done by achieving the invariance of coordinates that represent unwanted motiones with respect to ignored disturbances, as well as by isolating such coordinates from influences that destroy the desired invariance. Suppression of a parasitic motion components is carried out automatically. To do it, the structure and parameters of the system must be rationally selected, physically realizable and ensure its high dynamic qualities. It is convenient to choose the structure and parameters using the concepts of structural and parametric invariance. Their implementation is possible only if the two-channel principle is observed.
