Complexity, Volume 2026, Issue 1, 2026.The fixed‐time fault‐tolerant formation control (FTFC) issue is investigated for nonlinear multi‐USVs considering unknown dynamics, external disturbances, and time‐varying actuator failures. To further mitigate the burden on the channel, a nonmonitoring adaptive periodic event‐triggered quantized (NM‐APETQ) mechanism is devised, in which the quantized ...
