Is it possible to evaluate the differential equation from a simulink model?

Hello, I want to find the differential equation from the given simulink model:

I am not sure if i can get a differential equation from that picture

Answer 1

Hi,

The anwer is simple. 1/s means or its reverse means derivative. SO, the diff equations would be u_M(t) = dd(phi), d(phi)*k_M/J - phi*d/J =0.

Okay, thank you. But for me it is not really clear what this comma dd(phi), means?

I tried to write the formula a little better. Is this the formula you have given?

[Sulaymon Eshkabilov]

Not quite exactly. The SImulink model originated from two ODEs which are:

u_M(t) = dd(phi)

d(phi)*k_M/J - phi*d/J =0

Ah ok. Then the Simulink model has been build from two differential equations. I have understood it now. Thanks for the help.

Good luck.

Yes :)
