Course Evaluation
Theory
Quizzes 13 %
Midterm Exam 22 %
Final Exam 40 %
Laboratory
Lab Projects 25 %
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).


ExaminationsMid-term test: Week 7, Wednesday, February 28, 2024 (Date to be confirmed). It will be conducted online, as a take-home test, with individual versions, problem-solving questions, to be uploaded to D2L using Assignments feature. It covers Weeks 1 to 6.
 
 The final exam will be scheduled during the exam period, three hours duration. The exam is comprehensive, but with emphasis on the design aspects of the course, and is closed-book.
Other Evaluation InformationPlease note that the three labs are of different weights: 7%, 9% and 9%, respectively.
 
 Course evaluation includes both individual effort (midterm, final exam, D2L quizzes) and group work (lab reports, group activities).  
 
 In order for a student to pass a course with "Theory and Laboratory" components, in addition to earning a minimum overall course mark of 50%, 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.
 
Teaching MethodsELE639 lecture will be delivered in person. Classes are: Mondays (12:10 - 1:00 pm) in DSQ23, and Wednesdays (8:10 - 10:00 am) in DSQ10. All lab sessions are scheduled in person in ENG413.
 
Other Information1. All students shall adhere to the rules of Academic Integrity, and shall acquaint themselves with the Student Code of Academic Conduct and all other relevant policies. All relevant university policies found on Toronto Metropolitan University (TMU) Senate website: http://torontomu.ca/senate/course-outline-policies. Any suspected breach of Academic Integrity such as cheating or plagiarism will be investigated with the participation of the Academic Integrity Officer. Please check the course D2L website for more information on current policies.
 
 2. In accordance with the Policy on TMU Student E-mail Accounts (Policy 157), TMU requires that any electronic communication by students to TMU faculty or staff be sent from their official TMU email account.
 
 3. There are three projects to be completed in the lab - two computer simulation projects (SIMULINK & Matlab) and a real-time control experiment with a servomotor. The first two lab projects (simulations) focus on the stability and performance analysis on the PID Controller, and the third project is the feedback control design of the DC servo motor system in the Control Systems Lab (ENG413). In simulation projects, students will work with unique data sets that are frequently modified. Labs 1 & 2 are to be completed in pairs. Lab 3 is to be completed in groups of four. Simulation projects (Lab 1 & 2, and Part A of Lab 3) are expected to be completed mostly outside the lab. For the real-time experiment in the Controls Lab (Part B of Lab 3), students have to take measurements on the servo that is only accessible during scheduled lab hours in ENG413. All partners shall contribute equally to the lab reports. All lab reports have to be uploaded to D2L via Assignment feature before the start of the lab session when the report is due.
 
 4. Please note that the lab report marks may be adjusted at the end of the course to equalize differences between sections and different Teaching Assistants' grading styles.
 
 5. All of the required course-specific written reports will be assessed not only on their technical/academic merit, but also on the communication skills exhibited through these reports.
 
 6. All assignment and lab/tutorial reports must have the standard cover page which must be signed by the student(s) prior to submission of the work. Submissions without the cover page will not be accepted. Cover pages for each ELE639 lab experiment can be downloaded from the course D2L shell. Students can also use a Standard Assignment/Lab Cover Page found on the departmental web site.

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.
