CHE3162 - Process control
6 points, SCA Band 2, 0.125 EFTSL
Undergraduate Faculty of Engineering
Leader(s): K Hapgood
Not offered in 2009
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.
After completion of this unit, the student should be able to:
- understand the response to a disturbance including first order and second order responses
- analyse common control scenarios including feedback, feed forward, ratio and cascade systems
- analyse and model simple dynamic systems and understand the approach to modeling more complex systems
- apply basic and advanced control strategies including tuning of controllers, and model-based control
- appreciate the issues associated with the use of computer control systems for the implementation of process control
- analyse a process and select a suitable control strategy for a given situation
Examination (3 hours): 70%
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. Students failing to achieve this requirement will be given a maximum of 44% in the unit.
2 hours lectures, 3 hours of practice sessions/laboratories and 7 hours of private study per week
