Control of Electric Drives

Name of the Curricular Unit: Control of Electric Drives

Lecturer: Sérgio Cruz (smacruz@deec.uc.pt) 


Electric drives: typical configuration; motors and power electronic converters for drives. Typical structure of AC drives based on induction motors, permanent magnet synchronous motors and switched reluctance motors. Open-loop and closed-loop control of an electric drive. Scalar versus vector control: V/f control, Field Oriented Control (FOC) and Direct Torque Control (DTC). Configuration of the control system of vector control based drives. Tuning rules of the current and speed controllers. Estimators for drives: flux estimation, electromagnetic torque estimation and speed estimators. Sensorless control of electric drives. Self-commissioning.

Evaluation method: 

Project of research and synthesis about a given subject - 50%; Final exam - 50%.
