In　order　to　satisfy　the　requirements　of　higher　accuracy　and　faster　response　of　complex　system,　a　control　strategy　with　self-coordination　multimode　based　on　P　control,　fuzzy　control,　PI　control　and　online　genetic　optimization　is　presented　in　this　paper.　The　results　of　simulations　show　that　this　method　improves　not　only　the　disturbance　resistance,　shortens　the　transition　time,　accelerates　the　dynamic　response,　but　also　has　good　anti-interference　and　disturbance.　So　this　method　has　better　use　value.　©　2006　IEEE.
