The stability criteria for linear systems
O.P.D. Cutteridge · Proceedings of the IEE Part C Monographs · 1959
It is shown that the various stability criteria for linear systems can be conveniently obtained, and interrelated, by means of continued fractions. A new canonical form for a Hurwitz polynomial as a product of continued fractions is also given, together with an alternative set of determinantal criteria with determinants of about half the order of the Hurwitz determinants.
