Derivation of the linear models for the analysis of the plasma current, position and shape control system in Tokamak devices

The plasma current, position and shape control subsystem in Tokamaks (especially in tokamak-reactor) is one of the key part in the overall control system of the devices. Therefore to synthesize such subsystem it is necessary to derive the simplified (linear) model of the control object. In this paper one of the modern approach to derivation of the linear models for the analysis of the plasma current, position and shape control system is considered. The problems of the adaptability of the linear models and comparison with other models are discussed as well.
