The static regulator of a tension of a cloth of a paper.

Abstract

The paper tension regulator is considered, which with the help of a paw sliding on the paper controls the tension of the paper and affects the input of the speed control system of the paper machine section. The regulator circuit includes a thyristor reversible amplifier with a frequency-pulse control. Due to the application of the private-impulse principle of thyristor control, we obtain an integral control law, as a result of which the paper tension control system turns out to be static to the main disturbances.
