  title={Computation of Normalized Coprime Factorizations of Rational Matrices},
  author={A. Varga},
We propose a new computational approach based on descriptor state space algorithms for computing normalized coprime factorizations of arbitrary rational matrices. The proposed approach applies to both continuousand discrete-time rational transfer-function matrices and shows that each rational matrix possesses a normalized coprime factorization with proper factors. The new method is conceptually very simple, essentially reducing the original factorization problem to one for proper systems. The… CONTINUE READING
