Title : PID control of the tension system for the helical wound superconducting cable production system
Abstract:
Energy efficiency, whose importance is increasing day by day for zero carbon emission, is prompting scientists to seek different solutions in this field. One of the most significant problems in this field is the losses in energy transmission, and superconducting cables are proposed to minimize these losses at high currents. Conductor on round core design for coated conductive tapes for low-temperature (-273 C°) superconducting cable design is the most studied superconducting cable design today. One of the most important issues here is the adjustment of tension force and angle in these helical-wound cables and the proper winding of the cable.
This study aims to achieve accurate tension and angle control for helical cables using an automatic control method. A servo motor system employing a tensioning system and a laser measurement system for this aim. The literature was reviewed, and measurements were taken using the necessary experimental setups to obtain the best solution parameters. The system's transfer function was derived using the system parameters, and suitable proportional integrated derivative (PID) parameters were obtained using the Routh-Hurwitz method for stability analysis. For this parameters the system stability checked with Bode and Nyquist plots. The system was simulated in MATLAB/Simulink to investigate its stable operation for different PID parameters and to determine by trying the best parameters for this system.
