In this paper we discuss the convergence of a stabilization algorithm based on a singular version of the discrete Riccati difference equation. This method is particularly appealing for large scale linear time invariant dynamical systems since one can nicely exploit the sparsity of such systems in order to reduce the complexity of the algorithm.
