What you will be able to do.

Control and instrument engineers, DCS configuration engineers, process engineers responsible for unit performance; experienced panel operators

On a typical unit a third of the loops are in manual, a third oscillate and the rest were last tuned at commissioning. This course teaches tuning as an engineering method rather than a trial-and-error art: identify a process model from a bump test, choose a closed-loop response with a defensible lambda, and check the result on the trend. Participants work on their own loops exported from the historian, so the second day doubles as the first loop-assessment pass for their unit.

  • Recognise the PID forms, units and options implemented in the site DCS and convert between them
  • Run and interpret a bump or step test and fit FOPDT and integrating models
  • Tune with IMC/lambda and SIMC rules for self-regulating, integrating and dead-time-dominant loops
  • Diagnose oscillation, stiction, hysteresis and poor tuning from routine trend data
  • Tune cascade, ratio, feedforward and override schemes in the right order
  • Set loop KPIs and a review cycle so tuning does not decay
Course outline

Day by day

Day 1

What a loop is for: variability, constraints and money · PID algorithm forms, units and DCS-specific options · process dynamics: gain, time constant, dead time, integrating processes · bump testing on a live loop · model identification in CeraPID · IMC/lambda and SIMC tuning · robustness and aggressiveness trade-off

Day 2

Level, flow, pressure and temperature loop characteristics · cascade, ratio and feedforward tuning order · override and split-range schemes · stiction, hysteresis and valve issues seen from the controller · loop-assessment KPIs: variance, oscillation index, saturation, time in manual · workshop on participants' own loops · tuning records and MOC
