A new modular plasma control system on a modern hardware for tokamak FT-2 has been developed. The paper describes the system design, the principle of the plasma position control via thyristor keys, and the operating modes. In April 2025, the first tests of the tokamak FT-2 with the new control system were conducted in the mode of pre-recorded scenario of currents in the control windings. The tests proved the operability of the new system. Future development will be aimed at implementing of an automatic plasma confinement mode. Keywords: tokamak, plasma, control system, FT-2.
