Abstract

In earlier Rastovic's papers [1] and [2], the effort was given to analyse the stochastic control of tokamaks. In this paper, the deterministic control of tokamak turbulence is investigated via fractional variational calculus, particle in cell simulations, and fuzzy logic methods. Fractional integrals can be considered as approximations of integrals on fractals. The turbulent media could be of the fractal structure and the corresponding equations should be changed to include the fractal features of the media.

Key words: fractional variational calculus, particle in cell simulations, fuzzy logic, Hamiltonian, tokamak
