An introduction to process dynamics and process control technology.

• Dynamic process modelling
• Process dynamic elements such as resistive, capacitive, first-order, oscillatory and dead-time elements
• Behaviour of systems of dynamic elements using MATLAB and Excel
• Control hardware including controllers, sensors and valves
• Basic feedback control concepts and the Proportional-Integral-Derivative controller
• Closed loop stability and empirical tuning of controllers
• Cascade, ratio and feed-forward control
• Control of unit operations
• Process automation and PLC logic

The course will be taught using a real-time approach involving the hands-on use of dynamic simulation using Excel and Matlab (or Python). It builds on Matlab and Excel skills from previous courses. (The course does not use the classical Laplace Transform approach).

Learning Outcomes

  • Students should:
  • Fully understand the need to name, date and clearly document all files, spreadsheets and computer programs.
  • understand the dynamics elements that affect the dynamics of a process such as first-order response, dead time, and capacity.
  • Be able to simulate using Excel and Matlab (or Python), the dynamics response of systems made up of typical dynamic elements.
  • Become familiar with some typical items of control hardware that are used in industry.
  • Understand PID control well enough to be able to simulate and tune a real process.
  • Be able to simulate more complex control including cascade, ratio and feed forward.
  • Know which control loops might be suitable for a range of unit operations.
  • Be able to define and simulate automation of a simple process with many steps.


ENCH298 (from 2016)

Timetable Note

36 lectures, 3 assignments, 2 labs, and 1 test. Attendance at all lectures is highly encouraged. Students who do not complete all assignments and the exam are much less likely to pass.
