REAL-TIME SIMULATION PLATFORM OF AN EMA LANDING GEAR BASED ON MULTIPHASE BLDC

Abstract

Current environmental concerns have led to the partial electrification of the air transport, following the well-known more electric aircraft (MEA) concept. In such aircraft, electromechanical actuators (EMA) are being progressively introduced to substitute hydraulic actuators. In EMA systems, multiphase technologies are gaining popularity due to their high power density and fault tolerance; however, complexity is increased. To accelerate the early development stages of such systems, real-time simulation can be considered. This work presents a real-time simulation platform for a landing gear EMA implemented in an RT-Lab digital simulator, where the multiphase power system is simulated in an FPGA.
