Instructor(s)Dr. David Xu [Coordinator]
Office: ENG320
Phone: (416) 979-5000 x 556075
Email: dxu@torontomu.ca
Office Hours: Monday 2-4PM
Calendar DescriptionA course on modeling, analysis and design of electric drive systems. The main topics include: modelling of dc/ac motors, dynamic and steady performance, reference frame, small signal (linearized) analysis, solid-state converters, motor speed/position control schemes, simulation and digital control techniques. The modeling, simulation and digital controller will be developed in this course to analysis and design advanced electric drive systems. Important concepts are illustrated with laboratory experiments.

Learning Objectives (Indicators)  

At the end of this course, the successful student will be able to:

  1. To analysis the drive system performance using concept of various engineering knowledge. (1c)
  2. To develop system models and perform simulation. (2b)
  3. To design the drive system based on the engineering requirements. (4a)
  4. To conduct drive system experiment and data analysis. (5b)

Course Evaluation
Theory
Theoretical: Midterm Exam 25 %
Theoretical: Final Exam 45 %
Laboratory
Laboratory: DC motor drives and digital control platform 15 %
Laboratory: Induction motor drives 15 %
TOTAL:100 %

Note: In order for a student to pass a course, a minimum overall course mark of 50% must be obtained. In addition, for courses that have both "Theory and Laboratory" components, the student must pass the Laboratory and Theory portions separately by achieving a minimum of 50% in the combined Laboratory components and 50% in the combined Theory components. Please refer to the "Course Evaluation" section above for details on the Theory and Laboratory components (if applicable).


ExaminationsMidterm exam is tentatively scheduled in week 7, three hours, closed-book.
 Final exam, during exam period, three hours, closed-book. Details will be announced in D2L.
Other Evaluation InformationTwo formal reports are required for the labs. Each report will be assessed not only on academic and laboratorial performance, but also on the communication skills exhibited.
Teaching MethodsAll the lectures and labs are in person.
Other Information1) The first lab may contain micro-controller control code and experiment. The sample code (in C language) will be provided in D2L
 2) A formal report is required for each lab. The reports should be submitted via D2L before the deadline.
 3) The laboratory component is not only evaluated based on the reports but also the lab performance during the lab class.

University Policies & Important Information

Students are reminded that they are required to adhere to all relevant university policies found in their online course shell in D2L and/or on the Senate website

Refer to the Departmental FAQ page for furhter information on common questions.

Accessibility

Academic Accommodation Support

Academic Accommodation Support (AAS) is the university's disability services office. AAS works directly with incoming and returning students looking for help with their academic accommodations. AAS works with any student who requires academic accommodation regardless of program or course load.

Academic Accommodations (for students with disabilities) and Academic Consideration (for students faced with extenuating circumstances that can include short-term health issues) are governed by two different university policies. Learn more about Academic Accommodations versus Academic Consideration and how to access each.

Wellbeing Support

At Toronto Metropolitan University, we recognize that things can come up throughout the term that may interfere with a student’s ability to succeed in their coursework. These circumstances are outside of one’s control and can have a serious impact on physical and mental well-being. Seeking help can be a challenge, especially in those times of crisis.

If you are experiencing a mental health crisis, please call 911 and go to the nearest hospital emergency room. You can also access these outside resources at anytime:

If non-crisis support is needed, you can access these campus resources:

We encourage all Toronto Metropolitan University community members to access available resources to ensure support is reachable. You can find more resources available through the Toronto Metropolitan University Mental Health and Wellbeing website.
