Can OpenModelica draw root locus?

Sep-11-10 15:38:41

Hi,

We are trying to use OM for automation teaching purpose, but we didn't figure out how to draw root locus on this platform.
Is there any module can fulfill this purpose? if not, is it possible to create one?
BTW, we are using SimForge as the simulation enviroment.

Thanks

Hi,

OpenModelica doesn't know how to do this by default.
As far as I can understand the math It might be possible to implement it in OpenModelica.
You need to extract the model equations and do some symbolic transformation on them to obtain the transfer function.
It could be also possible to get the model equations and do this transformation in another tool that knows how to handle this.

MathModelica by MathCore [http://www.mathcore.com/] has a Mathematica connection that can be used for this.

Cheers,
Adrian Pop/
