Objectives
The course unit aims to develop the competences required for the definition, design and performance analysis of process control systems.
Upon successful completion of the course unit, students should be able to define control strategies for chemical processes, design such strategies, and analyse the performance of controllers, including through simulation of their behaviour.
Program
1. Fundamentals of process control
1.1. Functions and objectives of process control.
1.2. Main control strategies.
1.3. Concept of control loop.
2. Functional elements of control systems
2.1. Measurement and process variables in the context of control.
2.2. Control action and final control element.
2.3. Functional structure of a control loop.
3. Feedback control systems
3.1. Feedback control.
3.2. Data acquisition and transmission in control systems.
3.3. Process modelling for control purposes.
3.4. Types of control and controllers.
3.5. Design and tuning of controllers. Quantitative performance evaluation based on integral error criteria, namely IAE and ITAE.
4. Applications in chemical processes
4.1. Case studies of control systems.
5. Simulation in process control
5.1. Modelling and simulation of control systems.
Theoretical/Practical and Computational Tasks:
- Mathematical Foundations for the Analysis of Control Systems
- Dynamic Modelling and Determination of Transfer Functions
- Controller Design and Tuning Using Classical Methods
- Control Station: Identification, Design and Performance Analysis of Control Systems
Computational Project: Modelling, Simulation and Control of Chemical Processes
Evaluation Methodology
Assessment in continuous evaluation is made through of a project computational task of design and simulation of a control system of chemical processes (30%), a final written test (30%) and a set of theoretical-pratical and computational tasks (70%). A minimum classification of 7 in any one of the three itens is required. In final evaluation periods, the assessment consists in a written and computational pratical test (70%) and in a project computational task (30%).
