Teaching methods

Hands-on Laboratory Sessions Using MATLAB/Simulink, Supported by Theoretical Lectures Providing the Foundations for the Laboratory Activities.

As concerns the teaching methods of this course unit, all students must attend Module 1, 2 on Health and Safety online.

Assessment methods

The examination consists of the development and presentation of a complete electric drive simulation and control project, following the design methodology presented throughout the course.

The assessment is based on the extent to which the drive performance requirements are satisfied through MATLAB/Simulink simulations, as well as on the justification of the adopted design choices and the applied design methodology.

Students with Specific Learning Disabilities (SLD) or temporary or permanent disabilities: It is recommended to contact the responsible University office in advance (https://site.unibo.it/studenti-con-disabilita-e-dsa/en). The office will propose any necessary adjustments to the interested students, which must, however, be submitted to the approval of the instructor at least 15 days in advance. The instructor will assess their suitability, considering the educational objectives of the course.

Teaching tools

Lectures supported by computer-based presentations.

MATLAB/Simulink-based numerical simulation environment.
