Implementation and industrialization of flow vector control

The growing interest in asynchronous drives is undoubtedly closely linked to the success of flux vector control in many industrial sectors (lifting, textiles, metallurgy, paper mills, mining, foundries, transport, etc.).

Thanks to the development of semiconductor components and the evolution of digital information processing techniques, the industrialization of the concept of flux orientation in an asynchronous machine can now meet increasingly demanding specifications, linked to production imperatives in terms of quality and quantity. This objective can only be achieved at the price of a control-converter-machine match that takes into account the technological constraints and the environment of the process to be driven.

The heterogeneity of variable-speed processing and the diversity of constraints require a symbiosis between automation engineers, electrical engineers, electronics engineers, mechanical engineers, computer scientists, instrumentalists and process specialists, to select solutions that guarantee high static and dynamic performance with the necessary degree of reliability and level of availability.

The principles and operation of the asynchronous machine and the principles of flux vector control are described in article [D 3 563]. The reader is also referred to this article for the bibliography.
