An overview of power reactor kinetics and control in load-following operation modes
Autor: Gašper Žerovnik, Dušan Čalič, Samo Gerkšič, Marjan Kromar, Jan Malec, Anže Mihelčič, Andrej Trkov, Luka Snoj
Publikováno v: Frontiers in Energy Research, Vol 11 (2023)
Previous work done on reactor kinetics and control in load-following operation modes available in open literature is reviewed. The analysis is focused on, however not limited to pressurized water reactors. Different approximations of the time-depende

Model predictive control of resistive wall mode for ITER
Autor: Boštjan Pregelj, Samo Gerkšič, Marco Ariola
Active feedback stabilization of the dominant resistive wall mode (RWM) for an ITER H-mode scenario at high plasma pressure using infinite-horizon model predictive control (MPC) is presented. The MPC approach is closely-related to linear-quadratic-Ga

Finite-word-length FPGA implementation of model predictive control for ITER resistive wall mode control
Autor: Samo Gerkšič, Boštjan Pregelj
Publikováno v: Fusion Engineering and Design. 169:112480
In advanced tokamak scenarios, active feedback control of unstable resistive wall modes (RWM) may be required. A RWM is an instability due to plasma kink at higher plasma pressure, moderated by the presence of a resistive wall surrounding the plasma.

Quadratic programs resulting from a model predictive control problem in real-time control context are solved using a dual gradient method. The projection operator of the method is modified so as to implement soft state constraints with linear and qua

Model predictive control of ITER plasma current and shape using singular-value decomposition
Autor: Alfredo Pironti, Marco Ariola, Gianmaria De Tommasi, Matija Perne, Samo Gerkšič, Boštjan Pregelj
Publikováno v: Fusion Engineering and Design
A model predictive control (MPC) scheme for ITER plasma current and shape controller (PCSC) is presented. The controller is able to control a large number of geometrical plasma shape descriptors using output-space reduction based on singular-value de

ITER plasma current and shape control using MPC
Autor: Samo Gerkšič, Gianmaria De Tommasi
Publikováno v: CCA
In plasma magnetic control schemes, comprising a cascade control scheme with a plasma current and shape controller (CSC) in the outer loop and a vertical stabilisation (VS) controller in the inner loop, the main challenges are: the suppression of pla

Plasma current and shape control for ITER using fast online MPC
Autor: Boštjan Pregelj, Samo Gerkšič, Marco Ariola, Matic Knap, Gianmaria De Tommasi, Matija Perne, Alfredo Pironti
In this work we explore the practical feasibility of using MPC for PCSC in the ITER tokamak, employing complexity reduction techniques and recently developed fast on-line quadratic programming (QP) optimization methods. A survey of the available QP m

Improving Reliability of Partition Computation in Explicit MPC with MPT Toolbox
Autor: Samo Gerkšič
Publikováno v: IFAC Proceedings Volumes. 44:9260-9265
The paper addresses the problem of numerical issues and degeneracies in the parametric quadratic programming (pQP) algorithm, used for computing partitions of explicit model predictive controllers (eMPC) with the Multi-Parametric Toolbox (MPT). We su
