Abstract:
Tokamaks are the most promising devices to obtain nuclear fusion energy from a high temperature, ionized gas (plasma).
The main advantages are that fuel sources are essentially inexhaustible, the fusion process is inherently safe, and no
harmful greenhouse gases are produced.
In a tokamak, the plasma, having the rough form of a torus, is magnetically confined through electromagnetic fields
generated by a set of `'poloidal field'' coils distributed around the vacuum vessel. Voltages are applied to these coils which
drive coil currents inducing the magnetic fields. This field interacts with the plasma to change its shape and position and to
induce plasma current.
The uncertainty of the mathematical model of the plasma dynamics, which is correctly described by a set of non-linear
partial differential equations, the vertical position instability typical of the most common plasmas, and the occurrence of
