Syllabus: 1) DC Machines: Modeling of dc machines including load inertia and damping. Modeling of machine driven from a converter. Design of current, speed and position controllers for closed loop operation. Detailed study of one design example. Multi- quadrant chopper driven dc drives. 2) AC Machines: a) Induction machines: Scalar control. Space phasors and modeling of three phase induction machines. Reference frame theory. 'abc' reference frame to 'dq0' reference frame transformation and vice- versa. Stationary to rotating reference frame transformation and vice- versa. Description of stator, rotor and synchronous reference frames. Field oriented control of Induction machines using space- phasor as well as synchronous reference frame theory approach. Differences between rotor flux and stator flux control or direct torque control (DTC) will be highlighted. b) Permanent magnet synchronous machines: Field oriented control of permanent magnet synchronous machines using space phasors and synchronous reference frame theory. Learning Objectives:
Develop and analyze a dynamic model of a separately excited dc motor model, its control structure and design current, speed and position controllers for both constant torque and constant power operation. Indentify and analyze different chopper topologies for to drive a separately excited dc motor in different quadrants. Develop and analyze an induction motor model suitable for a scalar controller and the different speed control schemes. Develop and analyze dynamic model of an induction motor using space phasor and reference frame theory approach suitable for vector control of induction motor for improved transient performance. Develop and analyze rotor and stator (DTC) control schemes. Analyze field oriented permanent magnet synchronous motor drives. About the instructor I am an Associate Professor in the department of Electrical and Computer Engineering with fourteen years of teaching and eight years of industry experience. I am a doctorate in Electrical Engineering specializing in modeling and fault diagnosis of electric machines. I have numerous journal and conference publications in this area and a book titled Electric Machines, modeling,condition monitoring and fault diagnosis that I co-authored with H. Toliyat, S. Choi and H. Meshgin-Kelk. I am also a senior member of the IEEE and a professional engineer in the province of British Columbia, Canada. I believe in learning from concepts. This will provide the logical connection among the equations and numerical examples and makes the learning process very smooth. This way your problem solving skills will become systematic and not a haphazard search for equations and plugging numbers for answers. I very strongly encourage your asking questions which will promote interactive learning.i look forward to our journey together over the next three months. The final grade obtained from the above marking scheme will be based on the following percentage-to-grade point conversion:
The rules for supplemental examinations are found on page 81 of the current 2012/13 Undergraduate Calendar. Term in which E Grade Was Obtained First term of Winter Session (Sept Dec) Second term of Winter Session (Jan Apr) Summer Session (May Aug) Application Deadline for Supplemental Exam February 28 in the following term June 30 in the following term October 31 in the following term Supplemental Exam Date May September January Deferred exams will normally be written at the start of the student's next academic term; i.e., approximately 4 months following the deferral of the exam.
Important Announcements: i) Only scientific calculators are allowed during examinations. Programmable and other sophisticated calculators are not allowed. ii) iii) Food and drinks are NOT allowed in the classrooms. Except for health reasons and family emergencies, the end of term exam cannot be rescheduled. ivi) The instructor is planning to maintain a class website www.ece.uvic.ca/~snandi where the powerpoint slides will be posted. However, regular updates may not be possible at all times.
