Subject Overview: This subject covers the dynamics and control of process systems. Students are introduced to the concept of feedback control, with examples of controlled and manipulated variables and control schemes in process plants. Time domain analysis of process dynamics is performed using linear ordinary differential equations, Laplace transforms, and transfer functions. The dynamic response of complex process plants, described using first and second order differential equations and time delays, are investigated. Students are introduced to frequency response analysis and Bode plots. The development of empirical dynamic models, and numerical simulation using MATLAB, is also covered. 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 the MATLAB Simulink software package. 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 (proportional gain, integral time, derivative time) on control system response is investigated, along with the Ziegler-Nichols and other tuning methods. Advanced control strategies including cascade control, time-delay compensation, feedforward control, and model-based control are developed, as well as techniques to control multi-loop systems. Digital control systems and control system instrumentation are also covered. Case studies illustrate how concepts covered in this subject can be applied to, for example, plantwide control.
Objectives: On completion of this subject students should be able to:
  • Understand the factors influencing the dynamic response of chemical processes to process system changes
  • Analyse and implement effective and efficient process control strategies for chemical processes
  • Three assignments spread throughout the semester (30%)
  • One three hour written examination at the end of semester (70%)
