A procedure to recover explicitly self-adjoint matrix Dirac systems on semi-axis (with both discrete and continuous components of spectrum) from rational Weyl functions is considered. Its stability is proved. GBDT version of Baecklund-Darboux transformation and various important results on Riccati equations are used for this purpose.

Comments
The paper is dedicated to the memory of Leiba Rodman and his results on Riccatti equations are actively used in the proof of stability. The procedure to solve inverse problem, considered in the paper, is based on the article arXiv:1105.2013
