Abstract

PURPOSE:To control the motor speed in order to prevent occurrence of an anomalous loop, by overlapping a specified auxiliary speed correcting signal upon the main speed correcting signal obtained by proportionally integrating the deviation of the unit tension from the aim unit tension. CONSTITUTION:The unit tension DELTAT acting on the rolled material 1 is detected by the unit tension detecting circuit 21, and is compared with the aim unit tension DELTATREF by the speed correcting signal arithmetic circuit 22, thus obtained deviation is processed by the proportional plus integral operation, and the main speed correcting signal DELTAN is produced as the output. The unit tension comparison circuit 31, to which the unit tension DELTAT is inputted, compares the unit tension DELTAT with two tensions DELTAT1, DELTAT2(DELTAT2>DELTAT1) smaller than the aim unit tension DELTATREF; thus obtained tension deviation is given to the auxiliary speed correcting signal generating circuit 32; the circuit 32 generates the auxiliary speed correcting signal DELTANA increasing at a constant rate with the time; when the unit tension DELTAT matches to the set value DELTAT2, the signal DELTANA at that moment is held by the circuit 32. The speed correction arithmetic circuit 33 controls the speed of the motor 5 f the rolling mill 2 taking the combined speed correcting signal DELTAN-DELTANA as the correction value for the speed reference.
