Distributed Electronic Control Architecture and Low-Latency Electronic Information Transmission Technology for eVTOL

Abstract

The distributed power units of electric vertical take-off and landing (eVTOL) aircraft impose higher requirements on control real-time performance and transmission determinism, while traditional centralized avionics systems suffer from bus delay accumulation and single-point failure risks. This paper conducts a collaborative design for distributed electronic control architecture and low-latency transmission technology: at the architectural level, it proposes a node placement strategy based on weighted graphs, multi-agent task decoupling and load balancing methods, and a triple-redundancy fault reconfiguration mechanism; at the transmission level, it designs a physical-layer scheme with shortened polar codes and cyclic redundancy check (CRC)-aided decoding, combined with time-sensitive networking (TSN) scheduling and edge-end collaborative compression; at the integration level, it constructs a co-flow conflict resolution model, mode-adaptive bandwidth allocation, and clock synchronization jitter suppression strategies. Verification results show that the proposed scheme can limit the end-to-end transmission jitter to within one percent of the control cycle.
