Control of tension device for coil winding

To improve efficiency of a coil winding machine, the speed of winding the wire is increased. Then the some problems occur with increasing the wire winding speed. For example, the wire is broken or stretched too much. This paper has a discussion a control of the wire tension to avoid these situations. At first, we set a tension device at the initial position. If the tension arm moves from the original position, we control an angle of the arm to keep an original position by moving the drive motor. As a result, the angle of arm and the tension of wire are kept at specified value with small error. By the simulation, we confirm effectiveness of the proposed controller.
