Compensation requirements for an automatic tensioning device used in winding superconducting coils/

This thesis investigates the applicability of a commercial controller for stabilizing an automatic tensioning device used in winding operations for large superconducting coils. Unsuccessful results with the commercial unit leads to the design of a compensation network. Root locus techniques are utilized in arriving at a suitable compensation network to stabilize the tension machine control system. Simulated tests of the system's response to a step input and to a pulse disturbance are performed using IBM's Continuous System Modeling Program.
