How　we　intervene　the　multi-agent　systems　(MAS)　without　changing　the　local　interactions　such　that　the　system　exhibits　the　expected　collective　behavior　is　an　interesting　and　important　topic.　In　this　paper,　we　will　investigate　the　intervention　of　a　class　of　MAS,　where　all　agents　move　in　three　dimensional　Euclidean　space.　To　guide　all　agents　to　move　with　the　same　expected　direction,　we　put　some　information　agents　(also　called　leaders)　into　the　system.　Different　from　jilt　the　heading　of　each　agent　is　determined　by　two　coupled　angle　sequences,　which　makes　the　theoretical　analysis　quite　hard.　By　estimating　some　characteristics　concerning　the　initial　states　and　applying　the　mathematical　induction,　we　will　provide　a　quantitative　result　on　the　proportion　of　leaders　needed　to　guarantee　the　expected　consensus.
