EG40HC: PROCESS CONTROL (2014-2015)

Last modified: 28 Jun 2018 10:27


Course Overview

This course focuses on the fundamental principles of control theory and the practice of automatic process control. 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. 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.

Details, including assessments, may be subject to change until 30 August 2024 for 1st term courses and 20 December 2024 for 2nd term courses.

Summative Assessments

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

  • Simulation of a control problem using Simulink
  • Control Lab
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%)

Formative Assessment

Solutions to tutorial solutions provided.

Feedback

Solutions to tutorial solutions is provided. Students are expected to ask for feedback on their level of understanding at the weekly feedback/tutorial sessions.
Tutorial questions will be handed in each week.
Students requiring feedback on the exam should make appointments within this session to see the Course Coordinator.
