3.3.1 Nonlinear 6-DOF Rigid-Body<br />

Equations of Motion<br />

Lagrangian Parameterization:<br />

Application of the Theorem 3.2 with M = M RB yields the following expression:<br />

C RB <br />

0 33 mS 1 mSS 2 r g b <br />

mS 1 mSS 2 r g b <br />

mSS 1 r g b SI o 2 <br />

which can be rewritten according to (Fossen and Fjellstad 1995):<br />

C RB <br />

0 33 mS 1 mS 2 Sr gb <br />

mS 1 mSr gb S 2 <br />

SI b 2 <br />

#<br />

Joseph-Louis Lagrange (1736-1813)<br />

In order to ensure that C RB (ν) = -C RB (ν) T , it is necessary to use S(ν₁)ν₁ = 0<br />

and include S(ν₁) in C RB<br />
