Objectives

- Knowledge and understanding: knowledge and understanding of the operation of electrical drives for electric propulsion systems, especially of their acquisition and control systems;
- Applying knowledge and understanding: designing acquisition and control systems of electrical drives for electric propulsion systems, identifying and selecting the most suitable peripheral devices, transducers and processing units;
- Making judgements: ability to adopt reasoned solutions in designing acquisition and control systems of electrical drives for electric propulsion, based on the specific application requirements and on the available degrees of freedom;
- Communication skills: ability to transmit information in a simple, concise and effective way;
- Learning skills: self-processing of information, especially regarding the definition of design specifications of acquisition and control systems used in electrical drives for electric propulsion systems.

Prerequisites

A basic knowledge of electrical machines, power electronics and electrical drives would be useful for better understanding the teaching content.

Contents

The course includes the following main topics:
- Electrical drives with Surface-Mounted Permanent Magnet Synchronous Machines (3 class hours, 3 hours of classroom exercises): operating principles, mathematical model, control system, classroom exercises using appropriate simulation software;
- Speed and position transducers (2 class hours, 4 hours of laboratory exercises): main typologies and features, Hall sensors, resolver, absolute encoder, experimental laboratory exercises;
- Current and voltage transducers (2 class hours, 4 hour of classroom/laboratory exercises): main typologies and features, Sigma-Delta converters, classroom and experimental laboratory exercises;
- PWM modulation (2 class hours, 4 hours of classroom/laboratory exercises): operating principles of pulse-width modulation strategies, command signal generations, classroom/experimental laboratory exercises;
- Electrical drive with a Surface-Mounted Permanent Magnet Synchronous Machine (1 class hour, 5 hours of laboratory exercises): architecture of the control algorithm in programming language (VHDL), signal acquisition, elaboration, and transmission, brief overview on programming fast processing units (FPGA), experimental laboratory exercises.

Teaching Methods

The course consists of 10 class hours in order to allow the student to acquire the knowledge of the electric drive equipped with a permanent magnet synchronous machine, most employed current, voltage, position, and speed transducers, pulse-width modulation, and control algorithm implementation by programming, in VHDL language, fast processing units (FPGAs). The course consists also of 20 hours of classroom/laboratory exercises, 6 hours of which are devoted to computer exercises by means of suitable simulation software, while the other 14 hours consist of experimental laboratory exercises: these enable the student to develop the ability to apply the knowledge acquired during the lectures, especially regarding the acquisition and control system design of electrical drives for electric propulsion systems. Teaching will be delivered mainly face-to-face, integrated and “augmented” with online strategies to guarantee a novel and inclusive attendance.

Verification of learning

Students will be assessed by means of a written and oral examination, namely a report of classroom and laboratory exercises carried out during the course to be discussed orally. In this context, a course attendance of 80% at least is required (24 hours). Students will have to demonstrate also a fair knowledge, understanding and ability to apply knowledge on the operation, acquisition systems and control of electrical drives for electric propulsion systems.
