Abstract
A multilevel control system of a tokamak-reactor should provide measurements of the physical and technological plasma parameters in real time under conditions of high radiation fluxs. For the control systems of the ITER tokamak-reactor, it is planned to use automatic control systems based on the Siemens S7 programmable logic controllers (PLCs) which can operate under these conditions. Along with the possibility of multilevel remote control of the equipment, the PLC provides timely responses in emergency situations without human involvement and adaptive control in real time. This article presents results of using the Siemens S7 417-4 controllers for external resonant magnetic field control in the T-10 tokamak in the regimes with increased electromagnetic fields and radiation fluxs in shots with ohmic and additional microwave plasma heating.
