Abstract

In the Frascati Tokamak Upgrade (FTU) machine, there are the following coils: the main transformer coil, the preprogrammed vertical field coil, and the feedback coil. In order to maximize the number of ports for diagnostics apparatus and additional RF heating, FTU has been designed without a massive cupper shell. Plasma displacements due to preprogramming failures or disruptions will be recovered by the vertical field generated by the coil. The plasma current is feedback-controlled by regulating the transformer current. To study the control laws and to optimize the regulation gains, a computer code based on the CSMP III (continuous system modeling program) has been used
