The course consists of two 75 minute lectures per week. The grade distribution for the course is given below.
|Mid-Term Exams||20%||One mid-term examination will be administered. The mid-term and the final exams are equally weighted.|
|Homework||10%||Six to eight homeworks are assigned during the semester.|
|Simulation Projects||50%||Three computer simulation projects will be assigned. The students submit completed Matlab/Simulink programs and reports. The projects are worth 20%, 20% and 10% for the three assignments.|
|Final Exam||20%||A non-comprehensive final exam is administered at the end of the semester.|
Vector Control and Dynamics of AC Drives – D.W. Novotny and T.A. Lipo, Oxford Science Publications, 1996.
This textbook is required.
Analysis of Electric Machinery – P.C. Krause, O. Wasynczuk and S. D. Sudhoff, IEEE Press, 1994
This textbook is optional.
Computer simulations will be assigned during the course related to the topics covered in the course. Students are expected to have access to Matlab-Simulink software; Matlab-Simulink will be the primary platform for the simulations. The assignments will be collected and graded.
