Objectives

AIMS:
This course unit aims to provide students with knowledge about the dynamic behaviour of industrial processes, as well as the necessary theoretical and practical knowledge to design and operate process control systems:
Concepts of systems dynamics associated to the operation of industrial processes; Philosophies of processes control; Concepts of instrumentation associated to processes operation; Concepts of theory control of linear systems by negative feedback and anticipation; Design of control systems by negative feedback and anticipation-negative feedback; Design of data acquisition and computer control systems; Simulation and operation of processes controlled by the computer; Concepts about industrial design of distributed control systems.

LEARNING OUTCOMES:
I- Worth of each component (scientific and technological):
Scientific preparation (to establish and develop scientific bases) – 40%
Technological preparation (application to design and operation) – 60%

II- Specific learning outcomes:
After the completion of this course unit, students should:
- understand the necessity to study and to be familiar with the necessary methodologies in order to study the dynamic behaviour of processes;
- understand the main philosophies of process control;
- be familiar with industrial instrumentation;
- know how to tune controllers in negative feedback systems and anticipation systems;
- know how to simulate a control system;
- be familiar with topics of inferential control and adaptive control;
- understand the stages and actions in the design of a control system;

Teaching methods and learning activities

Theoretical-practical classes will be based on the presentation and discussion of case studies.
Students will have to carry out group assignments.
Students will have the chance to use computer assisted learning programs of processes control.
They have to give a laboratory presentation on an equipment of a simple cycle control system.
Students will have information available on SIFEUP a total inveracity with the professors.
In order to carry out a self-assessment, students can use some exercises sheets, some of them solved, so that they can assess their knowledge. They can compare analytical solutions with results obtained using the computer with the use of simulation packages.

Evaluation Type

Distributed evaluation with final exam

Eligibility for exams

To be admitted to exams, students have to:
Attend theoretical-practical and practical classes (according to the rules), reach a minimum grade of 25% in each assignment and reach a minimum average grade of 40% in the assignments.
Students, who attended classes in the last two years, do not need to attend classes this year.

Calculation formula of final grade

See document on SIFEUP about the assessment.
Assessment components:
Assignments – P1 – average grade of the assignments - 30% of the final grade
Continuous Assessment – P2 - 10% of the final grade
Exam – P3 (70-P2)% of the final grade

To complete this course unit, students have to reach the following grades:
Final Grade: – CF20= (P1 + P2 + P3)/100*20 ≥ 9,5
Exam: ≥ 30%

Examinations or Special Assignments

Groups of two students have to do the following assignments:
Assignment 1 – Systems Dynamics
Assignment 2 – Instrumentation
Assignment 3 – Control
The assignment sheets will be roughly delivered two weeks before the deadline.
Additionally, groups of two students will have to give presentations on the themes of the course unit, followed by discussion.

Special assessment (TE, DA, ...)

An individual exam which cover all the themes of the course unit. It will be similar to the final exam; however the content will be different.

Classification improvement

An individual exam which cover all the themes of the course unit. It will be similar to the final exam; however the content will be different.
