Imposing stability in DMD

[baggepinnen]

It would be nice to have a mechanism to impose stability of an estimated Koopman operator. One such mechanism which is commaonly employed for subspace-based identification is https://www.researchgate.net/publication/3891703_Imposing_stability_in_subspace_identification_by_regularization for which there is an implementation here

Thanks for pointing this out. Would it be okay for you, if I adapt directly from the implementation in ControlSystemIdentification?

Also, I was reading this paper which is related and also imposes stability constraints.

You may freely take as much as you want from my implementation 😃
