Abstract The mo deling the Three Dimensional Linear Inv erted
P endulum Mo de D LIPM is derived from a general
three dimensional inv erted p endulum whose motion is
F or D walking c ontr ol of a bipedrobot we analyze
constrained to mov e along an arbitrarily de ned plane
the dynamics of a thr e e dimensional inverted p endu
It allows a separate controller design for the sagit
