Abstract:

This year is anniversary of 130 years induction motor (IM) invention. Today IM is the dominant motor on the market. This study attempts to give a review of the historical development of induction motor control systems, present condition as well as the future trends in the development of vector-controlled induction motors (IM) drives. The discussion focuses around various scalar systems and their characteristics, the developing stages of individual constitutive parts of the control system, as well as the domain of their application. The procedure of space vector modulation has been briefly described and its peculiarities and advantages have been discussed with regard to the classical modulation techniques. There has been given principled classification of the vector systems for controlling induction motors. By comparing the basic functional block diagrams of the direct schemes for vector control, the indirect schemes as well as the systems for direct vector control of the torque and the flux, emphasis has been put on the basic peculiarities and performances of individual systems and their application domains.
