Abstract

The paper covers some questions related with the problem of plasma stability in vertical direction in the MAST tokamak. General positions of the modern μ-analysis theory are briefly formulated. The technique of robust features comparative analysis for feedback controllers is presented. Along with PD controller designed earlier, the optimal LQG controllers are synthesized and used for comparison on their dynamical and robust features.
