Syllabus
Prerequisites: Fundamentals of electric machines and drives
Target skills and knowledge: The course gives specific skills on the design of AC motor drives. The dynamic behaviour of most important AC motors is analysed. Both conventional and advanced control techniques are applied to synchronous and asynchronous motor drives. A complete design example is carried out by a case study. Practical design hints, as well as analysis of critical factors, as parameter sensitivity and fixed point conversion in AC drives are given as well. An experimental activity at Mechatronics lab is included in the course.
Examination methods: Traditional
Assessment criteria: Written and oral exams.
Course unit contents: The course covers the modeling and the design of torque and speed control loops for industrial AC motor drives, starting from the study of three-phase voltage inverter and the compensation of its non-ideality. In addition to the traditional techniques, the course includes some advanced alternatives, according to the most recent research lines. They include parameters estimation and sensorless control techniques.
Planned learning activities and teaching methods: [1] AC motor drives: introduction and classification. Three-phase voltage-fed PWM inverters. Modulation strategies. Space vector theory. The problem of voltage measurement. Inverter non-linearity compensation. Electromagnetic and acoustic noise. Three-phase current control. Control in both stationary and synchronous frames. Hysteresis control. Predictive control.

Fault-tolerant PMSM drives. Interior Permanent Magnet (IPM) drives. Synchronous and reluctance PM motor drives. Model and equations. Operating points. Field oriented control. Flux weakening control. Sensorless control.
[3] Three-phase induction motor drives. Principle of operation. System equations in the general rotating reference frame. Rotor flux oriented reference systems. Block schematics. Torque equations. The field oriented control principle. Direct and indirect current-controlled FOC schemes. Open-loop vector control. Parameters estimation.
[4] Laboratory - Parameter identification of IM and PMSM motors. Speed and current control of PMSM and IM drives. Three-phase inverter, characterization, deadtime compensation.
