More Electric Aircraft (MEA), which is the developing trend of the next generation of aircraft, put forward high demands on the electric power system. Cyber-Physical Systems (CPS) are a kind of novel intelligent systems with computation resources and controlled physical objects tightly integrated and interacted in the future network environment. CPS have the characteristics of real-time, synchronous, security, efficient and autonomous. This paper first elaborates the notion, characteristics, operation mechanism and technical challenges of CPS. The strategy of CPS-based next aviation electric power systems is presented. Then, the architecture of aviation electric power cyber physical systems is established. Finally, key technologies of aviation electric power cyber physical systems, including data bus, control strategies, energy management, security analysis, modeling and simulation, standardized and so on, are discussed. And directions are pointed out to offer a reference for the application of CPS in aviation electric power systems.
