Hi everyone,
I'm writing to ask a question about a particular physical system.
After analyzing it, I have these differential equations (the simbol ' is for the derivative):
n*h'' = F*r - k1*h' - k2*h
n*x'' + (k3-k4)*x + m*k5*g = (n/r)*h'' - r*k4*h
Now I must put them into state space form. The first equation is quite simple, but I can't solve the second one, as there is a second derivative on the input (h'') and the "m*k5*g" term.
How do I have to consider them? Could anyone help me how to get the solution?
Thanks a lot!
M.
