Digital Methods of Synchronization for Electric Drive Unbound Mechanically

The article describes the comparative structures analysis of motions synchronization of middle and high power electric drives. It compares the structures of synchronization in the context of influencing the final operation of systems and hardware methods of synchronization according to application and maximal response. The mathematical tools are based on the approach of the motions division of each electric drives and of the presentation of its transfer function in the matrix form. The adjustment ranges and response of different system types are compared experimentally by an estimate of the data transfer response and of speed pulsation on low rotation frequency.
