EEE8154 : Control of Electric Drives

Semesters
Semester 1 Credit Value: 20
ECTS Credits: 10.0

Aims

To enhance the students understanding of electric drive systems. To show the relationship between the theoritical and practical aspects of the subject.

Outline Of Syllabus

Basic drive configurations and load characteristics. Four quadrant control; Dynamic braking and regeneration, Constant torque and field weakening strategies; Example for high bandwidth torque requirement.

DC Drives: motor modelling; state space models; inverter modelling; transfer functions; closed loop response of speed and position control; stability considerations on 2nd order drive model; cascade control structures; converter control with modulation index; armature current control; practical current control methods; digital speed control; integrator windup.

AC Drives: Induction motor drives; space vector theory; state space models; phase and reference frame transformations; generic vector control description; torque and flux decoupling control; indirect and direct vector control; stator current control schemes; standard and space vector PWM methods.

Advanced control concepts and computer simulation: unipolar and bipolar H-Bridge control in DC drives, performance of detuned vector control; e-frame based stator current control.

Case study: Study of a 24V digitally controlled drive system. Electronics design and control software issues.

Teaching Methods

Please note that module leaders are reviewing the module teaching and assessment methods for Semester 2 modules, in light of the Covid-19 restrictions. There may also be a few further changes to Semester 1 modules. Final information will be available by the end of August 2020 in for Semester 1 modules and the end of October 2020 for Semester 2 modules.

Teaching Rationale And Relationship

Synchronous and non-synchronous sessions provide core material and guidance for further reading. Computer based learning exercises reinforce the lecture content and provide an opportunity for students to develop industry related simulation and modelling skills. Laboratories provide students with practical experience of electric drives.
Alternatives will be offered to students unable to be present-in-person due to the prevailing C-19 circumstances.
Student’s should consult their individual timetable for up-to-date delivery information.

Assessment Rationale And Relationship

The assessment provides the opportunity for the student to demonstrate their understanding of the course material. The problem-solving aspects of the assessment enable the student to demonstrate that they are able to apply this understanding and their analysis and synthesis skills to novel situations
