Abstract

PURPOSE: To reduce the fluctuation of tension of the strip, by supplying the largely fluctuant starting torque soon after the start of the loop car through the speed control system, and by supplying the torque with the current to be set according to the compensational current reference during the period of normal speed up.
CONSTITUTION: The system is constituted of the first current control system consisting of the loop car driving motor 11, variable voltage source 21, current detector 22 and current control amplifier 23, and the first speed control system in which the amplifier 23 is connected to the output of the speed control amplifier 41 inputted with the speed feedback signal from the loop car speed detector 31. The difference between the inlet side speed reference 28 and the outlet side speed reference 29 are given to the first speed control system as the first speed reference, and additionally, the output of the current control amplifier 42 is inputted to the first speed control system through the maximum output limiter 43 and the junction 44 for the tension controlling action. The second current control system is constituted by connecting the tension current reference 24 and the compensation current reference 25 to the amplifier 42, and the second speed control system is constituted by taking the first speed control system as the minor loop.
