Plasma control in tokamaks

This paper discusses and solves problems in the present-day design of the plasma control system in tokamak. The most widespread approach to the design of the magnetic plasma control involves: (i) plasma static equilibrium calculations, (ii) linear models derivation, (iii) synthesis of the controllers for the feedback control of plasma parameters, (iv) control system simulation and (v) control system optimization based on the results of the nonlinear simulations. The good performance of the plasma current discharge in tokamak is achieved by ensuring precise control of the plasma current, position and shape.
