Description of Achievement and Assessment Methods

The module examination is adapted to the aspired learning results:

1. Based on graded preparatory tasks (homework), the students' ability to work independently into the subject matter and thus to acquire new knowledge, solve problems and develop models will be evaluated.

2. The review of activity-based competences (for example, implementation of control algorithm on the microcontroller) is carried out by means of comprehension questions and discussion during the execution of the experiment (conversation).

3. The ability to analyze and evaluate simulation results as well as logical thinking is checked by means of graded final report.

The final grade is calculated from the partial tests by applying the following coefficients:

- Experiments execution: 50% - Homework + Final report: 50%

Prerequisites (recommended)

It is highly recommended to attend the course “Fundamental Theory and Design of DC/DC Power Supplies” in the summer term in order to get the necessary theoretical background for the practical course.

In order to participate successfully in the module, knowledge is strongly required in the following areas:

- linear control theory,

- programming language such as C,

- basic knowledge of electrical machines,

- operation of simulation software such as MATLAB/Simulink.

For this reason the following modules should already be successfully completed before participation:

- Advanced Control

- Electrical Machines

- Power Electronics

Learning outcomes

After successful participation in the module, the student is able to:

- design and optimize controllers for brushless DC machine,

- understand the operation of power electronic actuators,

- use simulation tools (e.g., MATLAB / Simulink) to investigate the behavior of mechatronic systems,

-use the integrated development environment (IDE) (e.g. Keil or Microsoft Visual Studio) to develop the embedded code for brushless DC drives system,

- understand the operation of the microcontroller (hardware) and use the embedded code (software) to control the brushless DC motor,

- apply different measuring methods in the laboratory

- analyze and evaluate the obtained measurement data.

Contents

This module consists of a series of microcontroller-based experiments with the following content being covered: - Modeling and simulation of the permanent magnet motors (brushless DC motor) with MATLAB/Simulink,

- Field-oriented control (FOC) design and optimization for brushless DC drives system,

- Sensorless field-oriented control design for brushless DC drives system,

- Embedded code design for brushless DC drives system with/without sensor in the integrated development environment (IDE) (e.g. Keil or Microsoft Visual Studio),

-Applications in automotive drives.

Teaching and learning methods

In addition to the individual learning of the students, comprehensive understanding will be gained by applying theoretical knowledge in the practical experiments.

Media

Following forms of Media will be employed in this module: - Presentations - Instruction manual (script) with preparatory exercises - Experiments (laboratory setups, measurements, etc.)
