AC Drive Control System of the Wire Drawing Machine with DTC Control and Fuzzy Controller

One of the biggest challenges in wire drawing processes, is to keep the straining force of the wire almost constant of the allowed maximum. The paper presents a high performance variable speed AC drive with DTC control of an induction motor, using a Fuzzy controller for the winding mechanism of the wire drawing machine. The automatic system controls the straining force in the wire. PI and PI-Fuzzy control methods are applied to select higher performance one. The simulation results show that methods like PI-FLC are more efficient to decrease energy consumption and increase the performance of driving system. Using system modelling, it was proved that the proposed driving system has high efficiency and good stability of the working speed ranging 0-1200 m/min during acceleration and deceleration of the winding machine, without mechanical shocks that could cause the breaking of the processed wire.
