Electrical Systems Control

The main objective is to illustrate and implement, via numerical simulation, general automation principles for electrical energy conversion and processing systems. The aim is therefore to develop expertise in electrical system control by combining knowledge from electrical engineering and system control techniques in the broadest sense.

The first part of the course is devoted to presenting general control concepts from linear, nonlinear, and sampled-data control, as well as some key principles for energy conversion (vector control of electric machines and vector PWM for three-phase inverters). Students then divide into groups (pairs or trios) and choose a topic from a list, which they then simulate using MATLAB-SIMULINK. The process involves modeling and simulating the object to be controlled, followed by designing a control law that meets the specifications. Students must then test and evaluate the performance obtained. At the end of the sessions, each group writes a report detailing the steps taken and the results obtained.

List of topics offered:
