CHE3162 - Process control - 2017

This unit provides a thorough introduction to process control and simulation. The unit begins with understanding disturbances, why disturbances need to be controlled and possible responses of various systems to a disturbance. The selection of which variables to control, which variables to manipulate and approaches to interactions are covered, together with the most important types of control loops and computer control systems. Topics include common control scenarios - feed back, feed forward, and cascade systems; ratio control; tuning of PID controllers; single loop and multiple loop systems; interactions and decoupling; process simulation and advanced process control.

At the successful completion of this unit you will be able to:

1. Discern the response to a set-point and disturbance change, including first order and second order responses.
2. Interpret common control scenarios including feedback, feed forward, ratio and cascade systems.
3. Interpret and model simple dynamic systems and understand the approach to modelling more complex systems.
4. Execute basic and advanced control strategies including tuning of controllers, and model-based control.
5. Discuss the issues associated with the use of computer control systems for the implementation of process control.
6. Design a suitable control strategy for a given situation and process.

Assignments/tests/laboratory: 40% + Examination (2 hours): 60%

Students are required to achieve at least 45% in the total continuous assessment component (assignments, tests, mid-semester exams, laboratory reports) and at least 45% in the final examination component and an overall mark of 50% to achieve a pass grade in the unit. Students failing to achieve this requirement will be given a maximum of 45% in the unit.

2 hours lectures, 2 hours of practice sessions/laboratories and 7 hours of private study per week
