Objectives

The aim of this course is to train in the field of control of systems based on electric machines, supported on project in application domains such as electric power generation systems, electric mobility and industrial drives.

Learning outcomes and competences

At the end of the course, as learning outcomes the student should be able to:
- Analyze the requirements of such a closed loop system based on the analysis of active and reactive power flows;
- Analyze the main functions and architectures;
- Specify the technical characteristics of the system;
- Develop models for behavior analysis by simulation of power control systems, in particular by researching relevant literature, formulating hypotheses and testing solutions;
- Use a computer simulation environment as an analysis tool;
- Design closed-loop power system, framing control structures and methods and selection criteria of the systems studied in the course, and considering the interaction between the different subsystems and the compromises to be established in balancing the solution as well as the various phases of the system life cycle;
- Participate with their own work in a project developed in a simultaneous engineering team;
- Structure and prepare technical reports;
- Prepare and self-evaluate the content of an oral presentation.

Working method

Presencial

Program

1. Introduction to the control of systems based on power electronics. Several subsystems: power supply; direct current bus (DC); three phase power converter; electric machine / load (rotary, industrial or electric traction, electric network);
2. dq transform; active and reactive power control; vector control of alternating current (AC) electric machines (field orientation and direct torque control);
3. DC bus voltage control; Architecture and operation of three-phase power converter: sampling theorem, modulation techniques;
4. Power control systems: renewable energy production; electric mobility; industrial drives, in speed and position.

Teaching methods and learning activities

The lectures are expository, including in the development of the case study program.

The practical classes are of three types:
- Lessons of analysis of the various subsystems;
- Follow-up lessons related to the simulation of these subsystems using a software package, carried out in the laboratory.
- Classes to support the implementation of a project of an industrial control system.

Eligibility for exams

Students will only be admitted to the Exam (EX) if they attend practical/laboratory classes and if they reach a minimum mark of 40% in TP, TE and AO components.

Calculation formula of final grade

1. Evaluation Components:
- An interim mini-test in the middle of the semester;
- Practical work (TP), compulsory and with individual assessment, assessing the ability to design and implement, evaluate and critically analyze solutions, as well as participation in the work team;
- Presence and participation in the classes and home works and oral presentation (AO), to assess the commitment to follow the UC and the ability to communicate in public to a specific audience;
- Team project development process (TE): team organization; work planning and control; quality of documentation and technical report; Exam (EX), evaluating the ability to analyze the operation of power control systems, as well as the creativity and rigor in proposing solutions.

2. Weights of evaluation components:
- Practical work (TP): 30%;
- Work development and report (ET): 20%;
- Exam (EX): 50%. An intermediate quiz is worth 25%, incorporated into the weight of the exam. The student may waive the respective component on the first exam call.

3. Calculation of final grade (FG)
FG = 0.30*TP + 0.20*TE + 0.5*EX

Passing the course is subject to a minimum of 40% in all components.

All of the components will be graded from 0 to 20 rounded to the unit.

Special assessment (TE, DA, ...)

Working students, military personnel and students association leaders who did not attend to practical classes, will have to attend a practical exam.

Classification improvement

Only the component "Exam" can be improved in the appropriate dates.
