Continuous chemical processes are inherently dynamic systems – process inputs and outputs change in time. To accommodate this, modern plants require some form of automatic control. This subject equips students with the skills to understand how and why key process variables change in time, and to then design and implement effective control strategies to accommodate this.
Students are introduced to the concept of feedback control, with examples of control schemes for common unit operations. The development of dynamic process models is introduced, along with analytical and numerical techniques for process simulation. Process simulation is performed using linear ordinary differential equation models, Laplace transforms, transfer functions, and numerical methods. The response of complex process plants to common dynamic inputs is investigated. Students are introduced to frequency response analysis and Bode plots.
The process control component of the subject introduces the concept of closed loop transfer functions and the PID controller. Dynamic process simulation is performed using analytical techniques and with the numerical simulation capabilities of software packages including MATLAB Simulink. The stability of closed loop systems is analysed using techniques such as Routh stability analysis, the Bode stability criterion, and gain and phase margins. The effect of controller tuning constants on control system response is investigated, along with various controller tuning methods. Advanced control strategies including cascade control, time-delay compensation, and feedforward control are developed, as well as techniques to simultaneously control multiple process variables in multiloop systems.
The subject will cover feedback control schemes for common unit operations. Developing and using process simulators, including the application of Laplace transforms and transfer functions as well as the use of numerical simulation tools. Frequency response analysis and Bode plots. Simulation of closed-loop control systems and PID controllers. Closed-loop stability analysis and controller tuning. Advanced single-loop control strategies and multiloop control systems.

- Analyse and implement effective and efficient control strategies for chemical processes
- Analyse and tune feedback controllers effectively
- Demonstrate mastery of the mathematical modelling of feedback and other control loops
- Appraise different methods of implementing advanced forms of process control and identify the optimum solutions particularly considering multi-loop control
- Appraise how regulatory control systems interact with safety systems to keep large scale chemical infrastructure operating in a reliable, safe, sustainable and profitable fashion.

Inherent requirements (core participation requirements)
The University of Melbourne is committed to providing students with reasonable adjustments to assessment and participation under the Disability Standards for Education (2005), and the Assessment and Results Policy (MPF1326). Students are expected to meet the core participation requirements for their course. These can be viewed under Entry and Participation Requirements for the course outlines in the Handbook.
This subject requires all students to actively and safely participate in laboratory activities. Students who feel their disability may impact upon their participation are encouraged to discuss this matter with the Subject Coordinator and Student Equity and Disability Support.
