Description: The mathematical model of twochannel digital threemass control the system with a presence executive drives is made and taking into account resilient elements between the billow of engine, reducing gear and by a drive mechanism. Influence of change of parameters the mathematical model of paper-lapping machine as трехмасовой control the system is considered. Built dynamic descriptions and the calculation of dynamic descriptions is executed for three radiuses of unwinding of ribbon from a group. For transformation of analog control the system to digital the method of extrapolation of a zero order is utillized.
Keywords: paper-lapping machine, three-mass control the system, brake mechanism, equalization of the state, transient, moment of inertia, dynamic descriptions
