| 内容記述 | The plasma position and shaping, and the plasma current are controlled by poloidal field (PF) coils consisting of superconductors, and the fast plasma position change is controlled by in-vessel coils consisting of normal conductors on recent tokamaks. The coil current response for the voltage command value depends on the time constant of the coil. The in-vessel coils have a much faster coil current response than PF coils due to the short time constant. Therefore, the decoupling control between in-vessel coils and PF coils respecting each coil current response must be established. In this study, we introduce the issues given by the coupling of in-vessel and PF coils controls and demonstrate the improved control by the decoupling. | |||||
