EG 40HC
PROCESS CONTROL
CREDIT POINTS 10

Course Co-ordinator: Dr J Kiefer

Pre-requisite(s): EG3020 EG3575

Note(s): Available only to candidates following an Engineering degree programme.

This course focuses on the fundamental principles of control theory and the practice of automatic process control. The dynamic behaviour of process plants is reviewed and the need for the control established. The properties of stochastic processes are introduced. The basic concepts involved in process control are then introduced, including the elements of control systems, feedback/forward control, block diagrams, and transfer functions. The mathematical techniques required for the analysis of process control are covered, focussing on Laplace Transform analysis, before students begin to develop simple control loops for first order systems. Development to more general situations is made through the study of second order systems and the application of compensation including PID control. The control theory developed is applied to a range of chemical engineering problems using simulation tools. The random nature of process disturbances is then introduced into the control loop behaviour to study the effect of dynamics systems. Students complete a case study which is marked as part of the continuous assessment element of the course.

24 one-hour lectures, 6 one-hour tutorials and 3 two-hour practicals in total

1st Attempt: 1 two-hour written examination paper (80%), and continuous assessment (20%) made up from the following two elements:


Resit: Where a resit is offered, the mark reported will be 1 two-hour written examination (80%), and in-course assessment mark from the 1st attempt (20%)
