Abstract
The COMPASS plasma control system is based on the MARTe real-time framework. Thanks to MARTe modularity and flexibility new algorithms have been developed for plasma diagnostic (plasma position calculation), control (shaping field-control), and protection systems (central solenoid protection).
Moreover, the MARTe framework itself was modified to broaden the communication capabilities via Aurora. This paper presents the recent upgrades and improvements made to the COMPASS real-time plasma control system, focusing on the issues related to precision of the real-time calculations, and discussing the improvements in terms of discharge parameters and stability.
In particular, the new real-time system has given the possibility to analyze and to minimize the transport delays of each control loop. (c) 2014 Institute of Plasma Physics AS CR.. Published by Elsevier B.V.
