1. A method, comprising:
forming, by a coil forming operation using a coiling apparatus, a portion of a coil including a first lap of coil and a second lap of coil from a strip of metal, wherein the second lap of coil includes a protrusion;
capturing, by a first sensor during the coil forming operation, first coil data associated with the coil while the strip of metal is being rolled into the coil, wherein the first coil data includes data corresponding to a radial force from the coil applied to a roll when the roll contacts the protrusion;
capturing, by a second sensor during the coil forming operation, second coil data associated with the coil while the strip of metal is being rolled into the coil, wherein the second coil data includes data corresponding to a position of the coil when the roll contacts the coil;
determining, using the first coil data, the second coil data, and a circuit, a signal that corresponds to a roll force of the roll and a position of the protrusion; and
transmitting, to a hydraulic cylinder coupled to the roll, the signal, wherein after the signal is received by the hydraulic cylinder, the hydraulic cylinder causes the roll to exert the roll force, wherein the roll force is counter to the radial force of the coil,
wherein the circuit includes a set of self-tuning bandpass filters, and
wherein each filter of the set of self-tuning bandpass filters is associated with a harmonic of an angular speed of the coil.
