Control of Power Electronic Systems

2021/2022

Prerequisite/Recommended prerequisite for participation in the module

The module is based on knowledge achieved in Power electronics, Electrical machines and Modern digital control.

Content, progress and pedagogy of the module

Learning objectives

Knowledge

  • Have knowledge about modelling, analysing and simulating a system that must include a power electronic converter, a power source and an application, typically an AC electrical machine or an AC grid
  • Comprehension of the practical implementation and test of the designed digital controller for the selected system

Skills

  • Be able to apply a systematic design procedure for selection of a digital controller for the analysed system in order to meet certain performance requirements
  • Be able to verify the analysis and models by means of laboratory experiments or by using real measured data series
  • Have an innovative and entrepreneurial behavior giving value for the developed system/apparatus

Competences

  • Be able to control the working and development process within the project theme, and be able to develop new solutions within control in power electronic systems
  • Independently be able to define and analyse scientific problems in the area of control of power electronic systems, and based on that make and state the reasons for decisions made for instance with respect to their influences on the total system
  • Independently be able to continue own development in competence and specialisation

Type of instruction

Problem based project organised work in groups. The project can be a disciplinary project, a cross disciplinary project or a part of a multi-disciplinary project, where several groups from the department do different parts of a larger project. Finally, the project can also be a part of a so-called MEGA project where several project groups from more departments are participating, each doing their part of the large project to find a total solution.

The project must include a power electronic converter, a power source and an application, typically an AC electrical machine or an AC grid. The operating principles for the system must be described and a control problem is formulated, including key specifications.

A dynamic simulation model is made taking the relevant dynamics into account. Different digital control methods are designed, analysed and evaluated by means of the simulation model. At least one method is selected for practical implementation in a real system incorporating a power electronic converter, a power source and a load, and a real‐time digital control system based on a digital signal processor or a micro controller.

The whole system is tested and the developed control strategies are evaluated.

A workshop “PBL competence profile” to make an individual PBL competence profile is offered during the semester. More information can be found at www.ucpbl.net/education-courses/.

Extent and expected workload

Since it is a 15 ECTS project module, the work load is expected to be 450 hours for the student

Exam

Prerequisite for enrollment for the exam

  • An approved PBL competency profile is a prerequisite for participation in the project exam.
