abstract = {The aero-engine, with the multi-electric technology as its new feature, optimizes the system's multiple energy architecturesand significantly improves system maintainabilityand reliability, which is now a core component of the multi-electric aero-engine research field. As the power generation system jumps from the hundred kW level to the MW level, the high-power, highly integrated multi-node power distribution systemand the power-using system including high-power pumpsand actuators together constitute a complex multi-electric control system. This system is characterized by multi-nodesand superposition of dynamicand static changes, and is facing the challenges in different application environments. Based on the electrification foundation, this paper firstly classifies the source-grid-load architecture of the aero-engine multi-electrical control system, and elaborates on the basic concepts, compositional characteristics, and challenges of the source, grid, and load systems. Then, the source-grid-load integrated system is analyzed, and the research status of four key technologies, the lightweightand high-reliable motor technology, power conversion topologyand motor drive control, multi-node microgrid networkingand control research, and electromagnetic compatibility modeling analysisand suppression methods, is comprehensively analyzed. Finally, the development trend of source-grid-load systemand the layout of multi-position architecture are summarizedand the prospects are discussed to promote the development of aero-engine multi-electrical control system.}
