| Abstract |
This work presents an improved control technique for the resistance commutation control system used in wound rotor AC induction motors, utilized in the 100 tons cranes installed in the steel industry (SIDOR) in Ciudad Guayana, Venezuela. This system is based on a microcontroller. The rotor resistance selection algorithm takes into account the original speed feedback signal produced by the tachogenerator and combines it with three additional signals already present in the original hardware: the speed demand, the current regulator output and the speed regulator error, producing a much more efficient and reliable control system when compared with the standard systems used in the industry, avoiding the usual problems detected in the currently working systems, and keeping the added circutry as simple as possible. The experimental tests confirm the improved system performance. This solution is applicable to other wound rotor AC induction motor drives. |
