CHE3162 · Process control

Overview

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.

Assessment

The Handbook lists an examination for this unit.

Continuous assessment: 50% Final assessment: 50% This unit contains hurdle requirements that you must achieve to be able to pass the unit. You are required to achieve at least 45% in the total continuous assessment component and at least 45% in the final assessment component. The consequence of not achieving a hurdle requirement is a fail grade (NH) and a maximum mark of 45 for the unit.

Assessment details may change. Please refer to the assessment information in Moodle closer to the start of the teaching period.

Requisites

Learning outcomes

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.

Workload

The minimum total expected workload to achieve the learning outcomes for this unit is 144 hours per semester typically comprising a mixture of 3-6 hours of scheduled learning activities and 6-9 hours of independent study per week. Scheduled activities may include a combination of teacher-directed learning, peer-directed learning and online engagement. Independent study may include associated readings, assessment and preparation for scheduled activities.
