Overview

BRIEF DESCRIPTION OF THE UNIT:

Part A: Process Control

  • PID controller structure: ideal/parallel/series, position/velocity implementation of digital PID.
  • PID controller tuning: Ziegler-Nichols and Cohen-Coon, Internal Model Control with lambda-tuning.
  • Enhanced control: cascade control, feedforward control, multi-loop control utilising de-couplers, Smith Predictor.
  • Multi-loop interaction analysis using Relative Gain Array.
  • Real-time process optimisation using Linear Programming technique.

 

Part B: Model Predictive Control (MPC)

  • MPC control formulation: simple unconstrained optimal control formulation, general characteristics of MPC formulation, translation of MPC problem into quadratic programming optimisation problem, constant output disturbance observer model, infeasibility and softening of the constraints.
  • Practical MPC implementation considerations: empirical model development, usage of design/tuning parameters, implementation/commissioning of MPC.
  • Design of MPC control for typical CSTR chemical reactor as well as distillation column.

Aims

This course unit detail provides the framework for delivery in 2020/21 and may be subject to change due to any additional Covid-19 impact.  Please see Blackboard / course unit related emails for any further updates.

The course unit aims to:

1. Introduce students to the fundamental concepts of applied industrial process control, including cascade and feedforward control structures as well as the use of de-couplers.

2. Introduce students to the formulation and the main implementation details regarding Model Predictive Control (MPC) as well as the real-time process optimisation.
