The course is connected to the following study programs

Teaching language

English.

Recommended previous knowledge

Students are recommended to have completed:

  • MAS237 Actuations Systems 1

or another equivalent course that includes:

  • Electromagnetic principles. Electric and magnetic circuits.
  • Transformer operating principles and operation.
  • Principles and operation of AC servo motors with drive circuits. Functionality, features, and sizing of electric drive components.

Learning outcomes

On successful completion of the course, the student should be able to

  • explain the interaction between mechanical load, electrical machine, power electronics, and control in an electric drive system,
  • analyze single-phase and three-phase systems, space vectors, and dynamic models in stationary and rotating frames,
  • model and simulate PMSM and induction-motor drives in Matlab/Simulink,
  • design and assess field-oriented control (FOC), including current, speed, and field-weakening control loops,
  • estimate motor parameters from manufacturer data and/or test data,
  • select and dimension motors, converters, and gearboxes using load requirements, loadability, and manufacturer catalogues,
  • integrate developed models into a complete drive-system simulation, design the controller, and analyze performance in a project setting.

Contents

Phase 1 (weeks 1-8): Lectures and tutorials

  • Introduction to electric drives, mechanical load requirements, coupling mechanisms, AC systems, three-phase circuits, and space vectors.
  • Power electronic converters (DC-DC, single-phase/three-phase inverters), PWM/modulation, and semiconductor devices.
  • Dynamic models of PMSM and induction motors, torque production, field-weakening operation, and parameter estimation.
  • Field-oriented control (FOC) for PMSM and induction motors, including current control, anti-windup, delay compensation, and speed control.
  • Motor/drive selection using load requirements, loadability, catalogue-based sizing, and optimization methods.

Phase 2 (weeks 9-12): Project

  • Students reuse and connect models developed in weeks 1-8 to build a complete electric-drive system model.
  • Components (motor, converter, gearbox, and relevant auxiliaries) are selected from manufacturer catalogues.
  • A control system is designed, implemented, and verified in simulation for defined operating profiles and constraints.
  • Performance is analyzed with focus on dynamics, torque/speed response, current/voltage limits, losses, energy efficiency, and robustness.

Teaching and learning methods

  • Lectures and guided calculation/simulation sessions.
  • Digital tutorial submissions in Canvas/Matlab Grader are used for module unlocking and course progression.
  • Group project work with supervision and mandatory presentation.

Examination requirements

No approved tutorial assignments are required for exam admission. Tutorials are still run with digital submissions that unlock the next module and enable progression throughout the semester. Information will be given in Canvas at the start of the course.

Examinations

Written examination, 3 hours (60 % contribution to final assessment) and project report (40 % contribution to final assessment). Graded assessment.

Student evaluation

Course evaluation is carried out as a midterm evaluation in accordance with standard procedure in the quality assurance system, chapter 2.1.1., unless other information is given in the beginning of the semester.

Offered as a free-standing course

Yes. Subject to availability or capacity.
