This　paper　proposed　a　novel　fractional-order　Vicsek　model　(FOVM),　which　can　effectively　improve　the　convergence　performance　of　the　original　Vicsek　model.　Numeral　experiment　results　show　that　there　is　the　optimal　value　of　the　fractional　order　of　the　FOVM　with　which　the　self-propelled　particles　can　achieve　the　best　convergence　performance.
