Write the differential equations and solve them using simulink's tools like a big boy.

How use simulink?

Tell me, NOW

you won't succeed, give up now.

Asking someone on /sci/ to tell me how to do it was kind of a sign I'd already given up

FreebodyDiagramm and then choose a state space representation (I'm German and just translated what I learnd as "Zustandsraumdarstellung")

then solve it. With what part do you struggle with?

>>9640973
About to embarass myself

>>9640994
That looks like what I got for the state space representation, the piece of shit simulink is what I don't know how to do. How do I do the input (u matrix in state space)?

Thank you btw.

I will suppose you defined your matrices properly since I don't have enough info to be sure about your problem.
Concerning matlab, just plug the input right into the block called State Space Representation.
You can choose C = eye(order of state vector) to get every state as output. Then you can use the block called scope to visualize them.
You can name the signals in the scope if you want to have access to the data out of simulink.
Hope it helps

If you want help on modeling just state clearly where the system is fixed cause I cant see it on the drawing

How do you into simple Lagrangian mechanics?
Seriously, just write down the Lagrangian, solve for the various modes, then apply your state matrix and find the equations which describe the motions of your system.

>>9639904
You already have a Simulink bitching thread up op, stop spamming retard
how you do it is you RTFM

>>9640531
you don't even have to write the equations you can actually draw that shit in simulink and then plot z1 z2

>>9639904
build it for real, put tracers on the mases and a strip of paper moving behind it

That other thread isn’t me
