Summary
This module provides an appreciation of the dynamic behaviour of processes, effects of disturbances and single loop controllers, the features and constraints on choice of conventional process control instruments and equipment and a basis for process analysis and design using dynamic process models and dynamic simulation.
The main topics are:
• Process Dynamic Characteristics: 1st order, 2nd order and dead time
• Feedback Control Methods
• Controller Tuning
• Cascade & Feedforward Control
• Design Philosophy & Flow-sheeting
• Frequency Response
• Process Dynamics simulation with Simulink
The course consists of lectures, which will include problem solving and interactive computer modules (ICM). Problems are to be worked primarily at home by the students.
Target Students
Students registered in the Department of Chemical and Environmental Engineering only.
Classes
- One 1-hour seminar each week for 12 weeks
- One 2-hour lecture each week for 12 weeks
- One 2-hour computing each week for 11 weeks
Activities may take place every teaching week of the Semester or only in specified weeks. It is usually specified above if an activity only takes place in some weeks of a Semester
Assessment
- 20% In-class exam: In-class Examsys test
- 80% Exam (2-hour)
Assessed by end of spring semester
Educational Aims
To provide a basis for understanding the dynamic behaviour of a process system and the options available for its safe single loop control.Learning Outcomes
A2.1.3 Be able to apply the principles to the analysis of complex systems within a structured approach to safety, health and sustainability. It is desirable that throughout the programme the students should gain an understanding of the broad range of applications of the principles and develop the ability to analyse, model quantitatively and synthesise at the appropriate scale. Assessment: Through written exam, using the real world case studies.
A2.3.2 be competent in the use of numerical and computer methods, including commercial software for solving chemical engineering problems (detailed knowledge of computer coding is not required).
Assessment: Written exam and ROGO test
A2.3.3 Be able to select and adapt computational and analytical techniques to tackle complex problems.
Assessment: ROGO test
A4.2.11.1 Detail design of control systems based on process dynamics
Assessment:This is achieved via workshop where Simulink is used to study the process dynamics and calculate the tuning parameters of a PID controller and assessed via a ROGO test.
A2.5.3 understand system dynamics, being able to determine the dynamic response to changes in a process, design measurement and control functions, and determine its performance.
Assessment: Written exam and ROGO test
A2.5.4 Be able to apply digital techniques to solving chemical engineering problems.
Assessment: ROGO test.
A2.5.5 Understand the benefits and risks of digitalisation and adopt a holistic and proportionate approach to the mitigation of security risks using process, cyber and automation, and behavioural measures.
Assessment: Through written exam, using the real-world case study.
A2.6.5 Be aware of specialist aspects of safety and environmental issues, such as noise, hazardous area classification, relief and blowdown, fault tree analysis.
Assessment: Students become aware of the hazards and able to implement safety measures such relief valves etc. This is assessed through written exam, using the real-world case studies.
