Advances in detector speed and resolution at 4th generation light sources make electron beam stability a critical requirement. At Diamond-II, the fast orbit feedback (FOFB) will stabilise the beam using 252 beam position monitors and two actuator arrays of 252 slow and 138 fast correctors. We previously proposed an approach based on the generalised singular value decomposition (GSVD), a...
Automation within the control system environment is a strategic goal at the European XFEL facility for various reasons: staff can be allocated more efficiently, procedures can be standardized to increase data quality, operator errors are minimized, and less experienced users can operate instruments. Prime candidates for automation are often recurring procedures during facility operation, such...
Quick-scanning Double Crystal Monochromator (QDCM) is core equipment of the Quick-scanning X-ray Absorption Fine Structure (QXAFS) experimental method. To realize the sub-second temporal resolution of QXAFS method, QDCM is responsible for achieving a reproducible oscillatory movement of monochromator crystals with a given frequency and amplitude around Bragg angle. A new robust controller...
Cooling plants are energy-intensive systems which enable ideal thermodynamical conditions for the smooth operation of accelerator facilities. Among this class of plants, chilled water production systems, used to bring cooling water from high to low temperatures, are commonly found. The automatic control system of such plant is usually complex due to the large number of correlated control...
The PETRA-IV Fast Orbit Feedback (FOFB) system will be a large-scale Multi-Input Multi-Output (MIMO) control system, utilizing 790 Beam Position Monitors (BPM) and 560 Fast Corrector Magnets (FCM) to maintain the desired orbit trajectory. Data acquisition and distribution will be managed across 16 supply areas and connected via an extended star network topology. This contribution focuses on...
