Fossil fuels (oil, gas, coal) currently represent about 85% of the world's primary energy sources, despite their expected depletion in a few decades and the CO2 greenhouse effect generated by their combustion. Controlled thermonuclear fusion by magnetic confinement, as achieved in tokamaks, is one of the potential options to provide a sustainable solution to our energy needs. Tokamak control issues are becoming increasingly important for the success of magnetic fusion and will be crucial for ITER, the world's largest tokamak under construction in the south of France. Feedback control of the plasma's main macroscopic parameters is now reasonably well Coils and magnetic ux in a tokamak mastered in various tokamaks worldwide, unlike the control of the plasma's internal radial profiles, crucial for ensuring both tokamak operation safety and the maintenance of...
