In　this　paper,　a　May　cooperative　system　with　feedback　controls　is　proposed　and　studied.　The　dynamic　behaviors　of　the　system　are　discussed　by　using　the　Lyapunov　function　method.　If　b(i)　not　equal　0,　i　=　1,　2,　we　show　that　feedback　control　variables　have　no　influence　on　the　global　stability　of　the　unique　positive　equilibrium　of　the　system,　which　means　that　feedback　control　variables　only　change　the　position　of　the　positive　equilibrium　and　retain　its　global　stability　property.　If　bi　=　0,　i　=　1,　2,　we　can　make　the　system　which　has　a　unique　globally　stable　equilibrium　or　has　unboundedly　large　solutions　become　globally　stable.　Some　examples　are　given　to　illustrate　the　feasibility　of　the　main　results.
