Experimental research of asynchronous electric drive with positive dynamic feedback on stator current

The article presents the results of a study into the asynchronous electric drive with positive dynamic feedback on stator current. The experiments were carried out with external analog processing and generating a control signal unit and the programmable logic controller. Correction algorithms are based on previously conducted theoretical studies and computer modeling. The resulting diagrams of transient processes confirm that the proposed correction in static modes is much more efficient than the traditional IR-compensation, and the reaction to the load sketch exceeds the closed-speed electric drive by dynamic characteristics. The ndustrial equipment by Schneider Electric - Frequency converter ATV71 and PLC Modicon TM241 - was used as a pilot.
