Practical Process Control Techniques

This popular 3-day course is a must for people who want to polish up their regulatory control skills and get some hands on experience with loop tuning. The agenda also covers design of Advanced Regulatory Control with an introduction to higher level technologies. Attendees from a range of disciplines (process engineers, instrument/electrical engineers, instrument/DCS technicians, industry consultants and process control engineers) have benefited from the blend of practical techniques explained through the use of real life examples and simulation exercises. A detailed course agenda is provided here.

Course Content

DAY 1
  • Process Control context – objectives, benefits, threats, terminology and structure.
  • Process Responses – types and measurement.
  • Data analysis – sampling, noise and filtering.
  • PID feedback control – PID components, equation types and tuning approaches.
  • Tuning techniques – flow, pressure, temperature and level tuning approaches.
  • Loop performance and instrument vulnerabilities.

Exercises to focus on:

  • Response definition and appropriate use of filtering
  • Use of the free Tune Wizard tuning tool
DAY 2
  • Dealing with Deadtime – tuning and model based control.
  • Cascade control – initialisation and anti-windup issues.
  • Process non-linearity and how to deal with this.
  • Constraint control and ratio control.
  • Dynamic compensation and feedforward control.

Exercises to focus on:

  • Diagnosing loop performance problems
  • Issues associated with tuning level loops manually
  • Design of cascaded loops and solutions to non-linearity
