Optimization of the TCV Advanced Plasma Control System (APCS).

·         Tests to the plasma vertical positionobserver were made with improved estimation of the plasma position using the new observer.

Plasma Vertical Stabilization Control

·         Development of plasma models to test the control algorithms for the plasma vertical stabilization.

·         Analysis of the use of optimal control theory to the controller under development and mathematical resolution of the application of minimum time control to a first and second-order system, applied to the plasma models.

·         The full definition of the controller and the simulation result analysis is ongoing.

During the year of 2011 Nuno Cruz visited the “Centre de Recherches en Physique des Plasmas” to collaborate with the TCV Control Team and to participate in some TCV Scientific Campaigns.
