Python module for application of (Hinf-)LQG-balanced truncation for low-order controllers for the stabilization of Navier-Stokes equations.

As an example we consider the stabilization of the cylinder wake at moderate Reynoldsnumbers via boundary control and distributed observation.

Documentation goes here.

Installation (including all dependencies, except from FEniCS, mat73):

pip install .

Dependencies:

• numpy (tested with 1.13.1, 1.18.0, 1.19.4) and scipy (tested with 1.1.0, 1.5.2)
• dolfin (python interface to FEniCS, tested with 2019.2.0 and 2018.1.0)

and my home-brew modules that are available via pip

pip install dolfin_navier_scipy
pip install sadptprj_riclyap_adi
pip install distr_control_fenics 

and on github:
