Abstract

1,033,227. Automatic control of tension. WESTINGHOUSE ELECTRIC CORPORATION. June 5, 1964 [June 28, 1963], No. 23399/64. Heading G3R. In a control system for a reversible rolling mill, wherein a strip 16 is passed between reels 22R, 22L, through rolls 12, 14, the tension in the strip is controlled in dependence on tension error, the integral of tension error, the acceleration and rate of change of acceleration of the strip. The rolls are driven by a motor 18 and the reels are driven or braked by motors 24L, 24R having their armatures supplied from Ward-Leonard generators 38L, 38R. The reel drives have similar control arrangement and for the left hand generator 38L a field winding 50L is energized from a bi-directional magnetic amplifier 54L having main control windings 66L, 70L and rate feedback windings 64L, 68L energized through a differentiating circuit 26L from the generator output. The main control windings are energized from a proportional integrator 80L, comprising a summing circuit 86L at the input to a high-gain D.C. amplifier 84L, having a rate negative feedback circuit 87L, the output of which is proportional to the input plus the time integral of the input. The summing circuit 86L is differentially responsive to a D.C. signal from a tensiometer 94L coupled to a deflector roll 98L and a reference signal from a source 90L to derive a signal proportional to the tension error, and to a D.C. signal representative of the rate of change of acceleration of the strip derived through cascaded differentiating circuits 102, 100L from the output of a tachogene rator 104 driven by the roll 14. The output of the tachogenerator is applied through series resistors 110, 112 to similar circuits 100L, 100R in order to derive opposite sign rate signals for application to the separate reel drive motors one of which acts as a brake on a feeder reel while the other drives the take-up reel. The tension error and acceleration rate input signals produce at the output of the amplifier 84L a signal representative of the tension error, the integrated tension error, acceleration of the strip and the acceleration rate of the strip which is applied to the control windings 56L, 70L.
