||Final written exam; homework helps to pass the course|
Advanced control techniques, such as field-oriented control (FOC) and direct torque control (DTC) have become the industrial standards in low-voltage (LV), and medium-voltage (MV) drives. The superior dynamic performance of the aforementioned control schemes, combined with their implementation simplicity, have enabled their widespread use. The objective of the course is to provide an understanding of advanced control methods for electrical drives. Exercises based on induction motor drives are used to consolidate the presented control theoretic concepts and to assist the learning process. Matlab/Simulink simulations further improve the understanding of the control methods, their benefits and intrinsic challenges.
