Course Goals

This course is an elective for both electrical engineering and computer engineering majors. The goals are to impart the dynamic modeling, simulation and control theory for electric machinery and associated power electronic drive systems that prepares students for electric power engineering careers and graduate school.

Instructional Objectives

A. After the first five weeks of class, the students should be able to do the following:

1. Perform magnetic analysis to obtain relationships between flux linkages and currents for dynamic models of salient pole machines. This includes machines with permanent magnet excitation. (1)

2. Derive expressions for the torque of electrical origin from the relationships between flux linkages and currents found above. (1)

3. Develop dynamic models for mechanical loads on electric machines. (1)

B. After the first ten weeks of class, the students should be able to do the following in addition to A above:

1. Manipulate dynamic models of machines with various transformations to obtain models suitable for analysis and control. (1)

2. Utilize systematic model reduction techniques to obtain time-scale separation in dynamic models for efficient simulation. (1)

3. Develop averaged models of power electronic supplies necessary for the design and simulation of electric machine control. (1)

C. After the full 15 weeks of class, the students should be able to do the following in addition to A and B above:

1. Simulate field-oriented vector control of electric machines. (1),(6)

2. Analyze the performance of electric drives and their controls. (1), (6)
