This paper proposes an adaptive web-tension controller that uses dancer arm position and take-up roller velocity sensors and a supply-roller torque actuator. The controller learns and cancels the effects of dancer arm weight, supply-roller friction, upstream tension, and dancer-arm and supply-roller inertia. Experimental results show reduction in the dancer arm angular error and tension variation by up to 500% and 300%, respectively, relative to P/D (proportional, integral, derivative) control.
