DESCRIPTION:Speakers: Nader Afshar (Controls Engineer)\nReliable\, robust\
 , and predictable control of motion axes is a key component to any synchro
 tron beamline. To this end\, new motion controls hardware (Geo-Brick-LV-GB
 LV\, Delta-Tau-UK) was recently introduced at the XAS\, IMBL\, SXR and XFM
  Beamlines. Challenges included optimising and tuning motion axes behaviou
 r for in-vacuum motors\, closed-loop tracking axes\, and scanners with vel
 ocity requirements. \nGenerally\, the GBLVs are very powerful motion contr
 ollers\, which can be utilised for many different applications by soft con
 figuration/tuning. This sophistication and flexibility often implies compl
 ex and potentially difficult configuration and tuning processes by highly 
 specialized engineers\, particularly for non-trivial motion environments a
 t beamlines. \nIn order to address these challenges\, a model-based approa
 ch was used to provide a framework for generalising and formulating the mo
 tion control system. The model makes it possible to classify applications 
 (e.g. positioning\, scanning)\, and suggest optimum motor configuration an
 d tuning based on design inputs of motor and stage specification and user 
 requirements (e.g. accuracy\, speed). \nThe model developed has been appli
 ed successfully to more than 50 motion axes at XAS\, IMBL and SXR\, adequa
 tely predicting motor performance outcomes. It strongly improves the class
 ical approach of system design based on expected configurations and manual
  tweaking in the field. This is because a model-based solution documents a
 nd incorporates learning\, evolves to handle more and more complex systems
 \, classifies problem types\, and\, importantly\, reduces non-standardisat
 ion while improving usability\, which ultimately benefits the user communi
 ty through more effective beamline operation.\n\nhttps://events01.synchrot
