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…mehr

Produktbeschreibung
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 controller unit is proposed and designed to dynamically change the motor drive reference angular speed according to the changing in winder radius and inertia to maintain a constant material tension and line speed. However, by this method the changing in tension of winder only can be overcome, but not its own zone. Also under any unexpected disturbance in any zone tension, the machine operation over all tension zones will be also disturbed. So to overcome this problem, this thesis further suggest a sensor-based tension controller designed to overcome such unexpected variation in tension.
