Abstract
The scope of this thesis involves various techniques to control the torque of a voltage source inverter-fed induction motor. The three methods investigated here are voltage by frequency, known as scalar control, field-oriented control with and without space vector modulation, and direct torque control. Although all three techniques have been proven effective, each technique possesses its own advantages and disadvantages. In todays engineering world, time and money are saved by utilizing software developed to accurately model a physical system and to compare with hardware previously implemented in a lab. Comparisons can be made to determine how each of these torque control methods perform under static and dynamic modes of operation. The United States military can benefit from this study by modifying or adding onto the software models developed here with little cost and use these models to do trade studies without the cost of lab demonstrations.
