Hello I'm wondering if anyone might be able to help me. I'm looking to model an equation using Simulink. I am given a transfer function instead of the differential equation which wouldn't be a problem except I need to alter the integrators and the transfer function in Simulink doesn't give me access to those. To work around that I believe I will need to model the differential equation instead. Since it is generally done the other way around I can't come up with a great way to do it at the moment. The transfer function is as below:

\(\displaystyle G(s)=\frac{-2s+8}{s^3+7s^2+14s+8}\)

Thanks for any suggestions!
 
[SOLVED] Re: Compute diff eq from transfer function

I have found a way to solve this, nevermind!

Click to expand...

Use partial fractions to break-up G(s) then use Laplace Transform.
