abstract
In this paper, we consider the design of tension control systems that employ both feedback and feedforward control actions to mitigate tension oscillations. A feedforward action directly compensates for any known behavior, nonlinearity, or disturbance in the system and allows for better error regulation by the feedback action. An example of feedforward action that is often employed is inertia compensation in web speed control systems. Adaptive feedforward actions that estimate periodic disturbances and provide compensation to mitigate tension oscillations will be discussed together with typical experimental results that highlight the effectiveness of these tension control systems.
