Controlled multi-motor drives

Controlled multi-motor drives are used in a great number of industrial plants. The functioning of large and complex systems such as ironworks, paper mills, excavators, etc. depends on the performance of the controlled multi-motor drives. A systematic survey of multi-motor drives based on the method of coupling and mutual influence is presented in the paper. Following that, an overview of the appropriate control algorithms, sorted by the principle of operation and the means of realization, is given. The paper is illustrated with selected applications of controlled multi-motor drives from the author´s practice
