Abstract
The central problem to be investigated in this paper is plasma optimal stabilization in tokamaks. Mathematical methods of stabilizing control design based on modern optimization theory are applied. Easy-to-find estimation of linear mean-square functional without need of direct solving the optimization problem is obtained. Particular problem of synthesis in the case of harmonic determinate disturbances is investigated.
