Modelagem e controle para acionamento de uma máquina síncrona para propulsão elétrica de aeronaves

Abstract

This work addresses the study of a hybrid-electric propulsion system for a small aircraft, focusing on the engine subsystem. This subsystem includes the DC bus, the frequency inverter and the permanent magnet synchronous machine, which will act on an aeronautical propeller. The work presents the mathematical and computational modeling of the plant in the MATLAB / Simulink software, where the designs of current and speed controllers are tested and validated. Furthermore, based on the Model-Based Design methodology, model-in-the-loop, software-in-the-loop and processor-in-the-loop techniques are developed, which stand out for the opportunity to optimize the time involved in the design and development of new technologies, being present mainly in the automotive and aerospace industries. Thus, through the methodology used, the control models in MATLAB/Simulink are developed to the control code that will be embedded in the Texas Instruments TMS320F28379D microcontroller. The TMS320F28379D through the processor-in-the-loop technique will be used to drive and control the virtual plant, making it possible to validate the implemented strategy so that practical tests can be performed in the physical plant. Simulation and co-simulation results are used to validate the modeling, controls and code implemented in hardware. While preliminary practical results will allow to verify electrical signals from the plant, in addition to the functioning of sensors and transducers. This work is part of the project entitled “Assembly of a Test Bench for Hybrid-Electric Aeronautical Propulsion” (APQ-03593-17), as a result of the collaboration between FAPEMIG, Embraer and UFJF, whose main objective is to develop national hybrid-electric propulsion technologies for aircrafts.
