Abstract：The electric control technology of the tension leveler, which was an important process equipment in the production of cold rolling sheet, was introduced. Based on the detailed analysis of the elongation and tension control modes of the tension leveler, the feedforward control was adopted to solve the instability and the hysteresis of the tension when increasing or reducing the unit speed in the tension control mode. Moreover, the problem of the large overshoot tension when shifting the elongation pattern to the tension pattern was solved by setting the definite value for the tension. The application results showed that the system ran stably and had high control reaction and accuracy.
