- Abstract
To control the plasma shape during a tokamak discharge, it is necessary to calculate the plasma shape in real-time. The rate requirements for the shape calculations are especially high for tokamaks with a small radius, such as Globus-M2 (St. Petersburg, Russia). A real-time magnetic plasma control system for the Globus-M2 tokamak with flux and current distribution identification (FCDI) algorithm for the plasma equilibrium reconstruction in feedback is presented. The control system contains discrete one-dimensional and matrix proportional-integral-derivative controllers synthesized by the matrix inequality method using the plasma LPV model calculated on experimental data, and carries out the coordinated control of the plasma position and shape as well as the compensation for the scattered field of the central solenoid. The FCDI algorithm is improved for the operation in the real-time mode, and makes it possible to reconstruct the plasma shape in 20 µs. The digital control system with a feedback algorithm was simulated on a real-time test bench, consisting of two Speedgoat Performance Real-Time Target Machines (RTTM), and demonstrated the average Task Execution Time (TET) value in 67 µs.
