INRODUCION Underwer gliders re ype of uonoous underwer vehicle (AUV) h oves by odifying heir buoyncy nd cenre of ss hrough n inernl oving ss. herefore, oion conrol is chieved by vrying hese wo preers, which re ypiclly conrolled hrough feedbck. o speed up convergence nd iprove perfornce, feed forwrd coponen y be used. However, n underwer glider is subjeced o vrious environenl disurbnces such s curren disurbnce. For exple, wer curren he surfce cn slide he glider fro is pre-se rjecory, which requires ddiionl conrol effor o bring i bck o desired ph [-3]. In order o reduce he energy consued on ph correcion during sedy gliding, i is very iporn o sbilize he desired ph. However, lile work hs been done on gliding oion sbiliy involving curren disurbnces which cn esily shif he glider fro is desired rjecory. However, lile work hs been done on gliding oion sbiliy involving curren disurbnces which cn esily shif he glider fro is desired rjecory. Leonrd [4] nd Nin [5] proposed LQR nd PID conroller respecively for oion conrol, bu boh of hese pproches were bsed on linerized dynic odel of glider nd he pplicion ws liied o equilibriu condiions.
