This unit builds on the previous Industrial Electronics courses EENG 27000 and EENG 37000 to investigate in more detail the performance and characteristics of electrical drives and in particular focusing on digital variable speed control of AC induction and permanent magnet machines.
Elements
Vector Based Control Prof P.H. Mellor
Review of the equivalent circuits and defining equations that describe the operation of AC machines. Discussion of the concepts of model order reduction and vector control. Develop mathematical descriptions of flux and torque control methods and their application to brushless AC permanent magnet and induction motors. Comparison with other control techniques.
Realisation in an Industrial Drive System Prof P.H. Mellor
Review the generation and characteristics of the various PWM techniques used in the voltage and flux control of AC machines. Develop typical torque and speed control structures used in AC drives and discuss their implementation. Illustrate the application of vector control through a case study on a typical industrial drive.
Sensors and Sensor-less Methods Prof P.H. Mellor
Introduce the need for sensors and the various types. Describe the operation, data processing, advantages and disadvantages of each type. Introduce position sensor-less techniques and discuss the suitability of these techniques
