In contrast to known approaches, no assumption is made about the presence of a special block structure in the original system. This allows systems with crossed connections to be considered. An example of the problem of longitudinal vibration control is given that permits analytical investigation of all constructions of the decomposition method.  Ключевые слова macrocontrols; systems with crossed connections; longitudinal vibration control; decomposition method
