The control system refers to the system that is in charge of monitoring and controlling all the sub-systems necessary to drive the facility. This will include a hierarchical distributed control system capable of operating the facility from a single location (the main control room).

It will, then, be possible to operate the facility according to its mission profile and to follow the time sequences, such as warm-ups, checks, alignments, and services, which are required to perform experiments. Operating the facility will include regular operation (availability and reliability) to drive the lasers, to perform experiments and retrieve experiment data, and to perform stand by operations (safety) and maintenance (repair, access, and maintenance).
The overall concept is for dedicated control sub‐system architecture with a distributed top‐level control system. Control sub‐systems for the buildings will include heating, ventilation, and air conditioning (HVAC) operations along with personal safety interlocks and will be integrated as stand-alone larger sub‐systems that use commercially available supervisory control and data acquisition (SCADA)‐type systems. The control sub‐system for security will provide access to control and monitoring.
The main control system will control individual beamlines and experimental equipment; it will be the one that drives and operates the facility.

The control system is divided into the following parts: the supervisory system, local systems for process control, the software integration platform, hardware and network architecture, and cable trays and wiring
