Strategy to systematically design and deploy the ITER plasma control system: A system engineering and model-based design approach

Federico Alberto Alfredo Felici, Richard Pitts, Federico Pesamosca, Anna Ngoc Minh Trang Vu

The paper details the process of developing the ITER Plasma Control System (PCS), that is, how to design and deploy it systematically, in the most efficient and effective manner. The integrated nature of the ITER PCS, with its multitude of coupled control ...

Overview of the TCV digital real-time plasma control system and its applications

Olivier Sauter, Basil Duval, Stefano Coda, Alessandro Pau, Federico Alberto Alfredo Felici, Alexander Karpushov, Antoine Pierre Emmanuel Alexis Merle, Joan Decker, Marcelo Baquero Ruiz, Artur Perek

Real-time plasma control systems are at the heart of operation of modern tokamaks. The control system of the TCV tokamak has recently seen a major upgrade in terms of its hardware and software components. Control algorithms are entirely programmed and test ...

Port-Hamiltonian observer for state-feedback control design

Anna Ngoc Minh Trang Vu

This paper extends the authors' previous work on Control by Interconnection - Model Predictive Control (CbI-MPC) design for constrained port-Hamiltonian systems to deal with the unmeasurable system states. The first contribution resides in the CbI-oriented ...

Overview of the TCV tokamak experimental programme

Olivier Sauter, Ambrogio Fasoli, Basil Duval, Timothy Goodman, Jonathan Graves, Yves Martin, Jean-Marc Moret, Stefano Alberti, Ivo Furno, Duccio Testa

The tokamak a configuration variable (TCV) continues to leverage its unique shaping capabilities, flexible heating systems and modern control system to address critical issues in preparation for ITER and a fusion power plant. For the 2019-20 campaign its c ...

A combined Control by Interconnection—Model Predictive Control design for constrained Port-Hamiltonian systems

Anna Ngoc Minh Trang Vu

This paper proposes a Control by Interconnection design, for a class of constrained Port-Hamiltonian systems, which is based on an associated Model Predictive Control optimization problem. This associated optimization problem allows to consider both state ...

Integrated Real-Time Supervisory Management for Off-Normal-Event Handling and Feedback Control of Tokamak Plasmas

Olivier Sauter, Alessandro Pau, Federico Alberto Alfredo Felici, Cristian Galperti, Anna Ngoc Minh Trang Vu, Bernhard Sieglin

For long-pulse tokamaks, one of the main challenges in the control strategy is to simultaneously reach multiple control objectives and to robustly handle in real-time (RT) unexpected events [off-normal-events (ONEs)] with a limited set of actuators. We hav ...

Control of NTMs and integrated multi-actuator plasma control on TCV

Olivier Sauter, Jean-Marc Moret, Federico Alberto Alfredo Felici, Antoine Pierre Emmanuel Alexis Merle, Cristian Galperti, Mengdi Kong, Francesco Carpanese, Anna Teplukhina, Federico Pesamosca, Emanuele Poli

The control of 2/1 neoclassical tearing modes (NTMs) with electron cyclotron (EC) waves has been studied both experimentally and numerically on TCV. Dynamic evolutions of NTMs along with time-varying deposition locations of the control beam have been studi ...
