Zusammenfassung:The invention discloses a method and system for attitude control optimization of an emergency parachute of an unmanned aerial vehicle, and the method comprises the steps: S1, building an attitude control system of the emergency parachute of the unmanned aerial vehicle, S2, converting the attitude control problem of the emergency parachute of the unmanned aerial vehicle into a mathematical model to be optimized, s3, setting the mathematical model to be optimized as an objective function of the improved myxobacteria optimization algorithm; and S4, introducing a captivity mechanism, firstly retaining a better solution by utilizing a greedy strategy, then setting a captivity range as a search range of next iteration by taking an optimal position as a center according to the position of the better solution, and performing iteration training for multiple times to finally obtain an optimal control parameter and realize attitude control optimization. According to the invention, by improving the myxomycete optimizatio
