Robust control of a high-temperature synchronous machine with anodized aluminum coils

Abstract

International audienceObjective – This paper presents a robust control strategy for wound rotor synchronous machine with anodized aluminum windings designed to operate at temperatures up to 300°C. At these high temperatures, resistance and magnetic flux can fluctuate significantly, challenging conventional control methods that depend on fixed machine parameters. This highlights the importance of a robust control strategy to effectively handle these variations.Findings – This control law has demonstrated its effectiveness in regulating machine speed and currents by enhancing the dynamics and reducing oscillations during steady-state operation. It also shows more adaptability compared to conventional control methods, such as Field-Oriented Control.Originality – Making a robust control for a high-temperature wound rotor aluminum coil machine by taking into account the losses and real-time parameters variations and estimating them. This problem is not a very present topic in the literature
