Hello all,

Im currently doing a project on non-linear control systems and I need
someone to just verify the derivation of the equation below.

[Image]I need to verify the derivation of the final equation using T and
U applied into the Euler-Lagrange equation. phi ' represents the
derivative of phi.

Also another matter is on how to convert the following equation into a
state space linear model.

[Image] where phi '' is the second derivative of phi and L' the first
derivative of L. The method will go about in assigning x1=phi, x2=phi '
and then doing the state space transformation into x'=Ax + bU where x
are the state variable matrices.

Yours,
Sri Kumar Kanajan
