Welcome to lqgbt-nse’s documentation!

This is a Python module for application of LQG-balanced truncation for low-order controllers for the stabilization of Navier-Stokes

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

To get started, install all dependencies, download the code from the linked github repository, create the subdirectory data, and run compscript.py. Since the problem already is unstable, the Newton-ADI iterations will not simply converge. You will need to compute stabilizing initial guesses first. Therefore, uncomment the respective line in the header of compscript.py.

Dependencies:

Alternatively:

If you have dolfin and scipy installed, all you need is in tar file attached to the github release v1.0-lqgbtpaper.
