Prerequisites: In order to acquire the skills and knowledge expected from this course, the following prerequisite are necessary: fundamentals of electric machinery (principles of torque production in electric motors), AC motor drives (three-phase inverter, field-oriented control of synchronous and asynchronous motors) and Automatic Control (time and frequency analysis of dynamic systems, feedback systems, stability analysis and design of control systems)
Target skills and knowledge: - Knowledge of the dynamic models of the main electric motors for industrial use and identification of the related parameters.
- Knowledge of torque and speed control techniques for AC motors even without the mechanical position sensor (sensorless drives).
- Ability in simulating the most important motor dynamic models and in designing and implementing the torque and speed control loops in Matlab/Simulink environment.
- Ability in writing a C code for a real microprocessor to implement a sensorless drive.
Examination methods: The verification of expected skills will be carried out by an oral examination. The discussion will start from two scientific reports written by each student.
The former report shall describe the sensorless algorithm as well as the simulation and experimental results.
The latter report shall describe the implementation of a recent AC electric drive technique implemented either in simulation, experimental setup or both. The proposed techniques deal with maximum efficiency operations, high-frequency injection based sensorless drives, predictive control, etc.
To access the acquired knowledge, the presentation of the two reports is followed by a discussion on the course topics.
Assessment criteria: The evaluation criteria used in the knowledge and skills verification are the following:
-Completeness of the theoretical knowledge acquired in the field of electric drives, with attention to the motor models, torque and speed dynamics control speed and sensorless drives.
- Degree of autonomy in the implementation of modern AC drive techniques.
- Ability in clear and accurate exposition of concepts
- Ability in the use of technical instrumentation and software.
Course unit contents: The specific contents of the course can be summarised as follows:
- Equations and dynamic models of induction motors and of PM synchronous motors with both isotropic and anisotropic rotors structures for their simulation on computers;
- Parameter identification in AC motor drives: methods and implementation;
-Software Matlab/Simulink for the simulation of systems based on problems described by ordinary differential equations.
- Simulation and implementation of torque and speed control loops, even without the mechanical position sensor.
- Current, torque and speed control techniques in industrial AC motor drives.
- Sensorless control implementation in C code on a real AC drive.
Planned learning activities and teaching methods: The course comprises the following activities:
- Theoretical study of the structure and models of AC motors drives and the related controls for their implementation in a simulation environment;
- Use of Matlab/Simulink to simulate the speed and current controls for AC motor drives including sensorless control;
- Tests of the simulated techniques on a real AC drive within the didactic laboratory of mechatronics.
Additional notes about suggested reading: The study material includes:
- lecture notes written by the professor;
- articles from international journals
All material will be made available on the Moodle educational platform.
