Is there an alternative to the Matlab command [systune](https://www.mathworks.com/help/control/ref/dynamicsystem.systune.html) in Julia?

> `systune` tunes fixed-structure control systems subject to both soft and hard design goals. `systune` can tune multiple fixed-order, fixed-structure control elements distributed over one or more feedback loops.

The goal is the optimization of a fixed structure controller to design a robust flight controller in the context of an MSc thesis.

This is the closest alternative I’m aware of

> Documentation for JuliaSimControl.

I think JuliaSimControl is closed source. Could I as postdoc or my MSc student get a free licence? How would that work?

It’s free for academic use, see [Using JuliaSim Packages Locally via the JuliaHub Registry · JuliaSim](https://help.juliahub.com/juliasim/stable/gettingstarted/juliahubregistry/) for installation instructions

And a license for a start-up company? Would that be the same license as a JuliaHub license, or would a license for JuliaSim be something differently?

Can JuliaSim be used locally, or only in the cloud?

See the first sentence on the link above

You’d have to contact sales for that, see info on the link above.

I contacted sales. Lets see what they say. If it is significantly cheaper than Matlab/ Simulink I would suggest it to startup companies. Of course there are other reasons than the price to use Julia and not Simulink, a major point is ModellingToolkit (MTK) which is very good.

They did not reply. Any idea why?

It was indeed in my spam folder. Sorry for the noise!
