A more open future for nuclear research
A growing number of institutional, national, and funder mandates are requiring researchers to make their published work immediately publicly accessible, through either open repositories or open access (OA) publications. In addition, both private and public funders are developing policies, such as those from the Office of Science and Technology Policy and the European Commission, that ask researchers to make publicly available at the time of publication as much of their underlying data and other materials as possible. These, combined with movement in the scientific community toward embracing open science principles (seen, for example, in the dramatic rise of preprint servers like arXiv), demonstrate a need for a different kind of publishing outlet.

The problem of designing a plasma current and shape control system for a tokamak is dealt with, and a complete framework based on a validated linearized plasma model is developed. Starting from the equilibrium configurations to control and given the required performance, a procedure for choosing the parameters to control is outlined. Then, a method is proposed to evaluate the best performance one could ever expect from a control system, given the actual limitations due to the power supply. A procedure for designing a linear controller is described. The use of a modern multivariable technique, such as the H theory, allows one to take into account the many existing constraints and to find a trade-off among performance, robustness, and control effort. The methodology proposed is general and can be applied in principle to any tokamak plant. The simulation results refer to the International Thermonuclear Experimental Reactor (ITER) tokamak. A controller designed following almost the same steps has been successfully tested on an existing tokamak.
