Abstract

The paper is devoted to the development of two-loop plasma position, current and shape control system in tokamak-reactor. The H_infin approach is used for the design of SISO and MIMO feedback controllers. In the procedure of controllers design the MIMO linear plant model (plasma in tokamak) DINA-L was used. The linear model was obtained from non-linear plant model realized by plasma-physics DINA code for ITER conditions. The set of simulations of closed-loop magnetic system was done on linear (DINA-L) and nonlinear (DINA) plant models when minor disruptions occurred. Simulations results for both models were superimposed and showed good coincidence at acceptable control system performance
