Problems #2

1. Discuss a complete speed control scheme for the Indirect Vector Controlled Induction Motor Drive. In the schematic diagram, identify the variables in the synchronously rotating reference frame.

2. Discuss a torque-controlled Induction Motor Drive with the Direct Vector Control type controller. Discuss different types of flux estimation techniques those may be used with Direct Vector Controlled type Induction Motor Drives.

3. How Direct Vector Control is different from Indirect Vector Control. Discuss the merits and limitations of these methods.
