This paper presents a method for modelling dynamic stiffening occurrin
g during the movement of large flexible structures. Specifically, the
paper presents a model including dynamic stiffening effects of an arbi
trarily shaped flexible body undergoing large overall motion. Control
is applied through variable structure control and sliding modes. Appli
cation with a space robot performing a tracking task is also presented
