In order to understand how people in the Julia community (and outside) make use of software for control-systems analysis and design, I’ve put together a little survey. Answers to this survey will help us improve upon and prioritize upcoming work in the Julia ecosystem for control.

> **[Control-systems user survey](https://forms.gle/ySdQ6f4iR44fs9Lt8)**
>
> Please share your usage of control-systems software!

The first part of the survey is completely anonymous, and the _less anonymous_ second part is _optional_.

If you work with control systems, please share this survey with your friends and colleagues.

Thank you for your contributions!  
Fredrik

Is there any package providing a discrete PID controller with a good anti-windup strategy?

ModelingToolkitStandardLibrary.jl has a nice implementation of a continuous-time PID controller with anti-windup

A discrete-time implementation is not yet available there unfortunately. I find that conditional integration, possibly with sign check for non-minimum phase systems, is usually effective for discrete time systems. Having a solid implementation of such a controller would be nice to have in the ecosystem!
