Abstract
Real-time techniques are crucial in tokamaks to stabilize plasma position and achieve longer discharges. ADITYA-U uses real-time feedback control of the equilibrium field to stabilize the horizontal plasma position and improve plasma parameters. This innovative control system, developed using the NI-PXI-7831R card in a PXI chassis, featured an integrated PID controller. The PID controller generates control signals for the fast-feedback coils, resulting in successful control of the horizontal plasma position. However, the initial control system had some limitations. Therefore, it was upgraded using the Compact-RIO (c-RIO), for better control and flexibility in adjusting PID parameters. This upgrade allowed for longer durations of discharge of ~400 ms and improved data retrieval capabilities. The full paper will provide more details on the upgraded system and its performance in the ADITYA-U tokamak.
