Getting constant tension control between multi coordinate drives of windier machine systems is the main requirement of many industrial production lines; including steel, textile and paper film printing machines. The most influenced parameter of such winding machine is the changing of unwind and rewind radius then changing the moment of inertia. Therefore, by the conventional method of motor controller that is depending on a constant reference torque and angular speed, unwind and rewind roll tension is changing due to the changing in roll diameter. In this thesis, an sensor-less tension control...
