Abstract

PURPOSE:To make possible the response speed to be quickened holding the stability of entire system, at the looper control in the continuous rolling mill, by sending the signal corresponding to the looper angle from the resonance-frequency-multiplier to the current reference of the torque motor as the feedback so as to raise the gain of the resonance frequency multiplier. CONSTITUTION:The looper angle detected by the looper angle detector 6 together with the deviation of the reference looper angle are inputted to the resonance frequency multiplier 14, which operates the resonance-frequency-multiplying-torque for obtaining the desired resonance frequency, and inputs the result to the looper- motor-current-arithmetic-unit 8. Besides, the rotational frequency of the looper motor is detected by the looper-motor-rotational-frequency-detector 15 and is inputted to the attenuation compensator 16 which then operates the attenuation-compensating-torque corresponding to the desired resonance frequency and inputs the result to the looper-motor-current-arithmetic-unit 8. This arithmetic unit 8 operates the looper-motor-current from above stated two inputs and the reference torque inputted from the looper-motor-reference-torque-arithmetic-unit 7, and causes the looper motor 10 to generate the suitable torque through the looper-motor ACR 9.
