TL;DR: A model predictive control (MPC) method for stabilization of the resistive wall mode (RWM) in the EXTRAP T2R reversed-field pinch is presented in this paper.

TL;DR: In this article, the authors proposed a frequency domain-based method for detection and optimal compensation of performance degrading nonlinear effects in Lur'e-type systems, where a sinusoidal response is necessary and sufficient to show the existence of an equivalent linear and time invariant dynamical model that fully captures the system dynamics for a well defined set of input signals and initial conditions.

TL;DR: In this article, a real-time performance optimization is achieved by application of extremum seeking algorithm, which yields a new method for realtime compensation of performance degrading nonlinear effects, which is successfully demonstrated in both simulation and experiment.

TL;DR: Many implementations of a model-based approach for toroidal plasma have shown better control performance compared to the conventional type of feedback controller.

TL;DR: In this paper, a new method for the estimate of the wall diffusion time of non-axisymmetric fields is developed and tested in EXTRAP T2R, which intrinsically considers the effects of three-dimensional structures and of the shell gaps.
