| Abstract |
This paper describes a new AC drive system for SENDZIMIR Cold rolling Mill. The roller, coiler and uncoiler ,are driven by induction motors supplied by three-level high-power GTO inverters with a common DC busbar. The drives are coupled mechanically by an elastic strip of metal. The AC variable speed drive of the high performance type is provided with the vector control and substitutes for the conventional DC variable speed drive. For the purpose of field-oriented control, Kalman filter algorithm is used to obtain the unmesurable rotor flux of a squirrel-cage induction motor. The relationship between motor drive performance, strip tension quality and strip thickness accuracy is investigated and verified through simulation. |
