7. A control system for forming a tapered structure, the control system comprising:
a sensor arranged to measure position information of a stock material moving into a curving device; and
a controller in communication with the sensor, the controller including one or more processors and non-transitory computer-readable storage media, the non-transitory computer-readable storage media having stored thereon instructions for causing the one or more processors to carry out processes including
receiving the position information from the sensor,
receiving, from a model stored on the non-transitory computer-readable storage media, relative positions of the stock material moving into the curving device,
determining a control signal based on the model and the position information of the stock material measured by the sensor, and
sending the control signal to an infeed adjustment mechanism to position the stock material moving into at least three rolls including at least one bend roll and at least two guide rolls of the curving device, the control signal moving the stock material about a peak of the tapered structure being formed as the stock material moves into the curving device.
