Abstract
A controller for a motor is configured to rotate a roll of material. The controller includes a drive speed regulator configured to generate an initial torque command based on a difference between a speed setpoint and a measured drive speed of the motor. The controller also includes an observer module configured to estimate a density error of the roll of material. The initial torque command is adjusted based on the density error to obtain a total torque command. The controller also includes a torque regulator configured to control the motor based on the total torque command.
