A geometrical interpretation of the Routh test

A Lepschy, GA Mian, U Viaro - Journal of the Franklin Institute, 1988 - Elsevier
A simple geometrical proof of the classical Routh test is presented. It is based on the
application of the root locus technique to suitable additive polynomial decompositions. The …

[图书][B] Fast algorithms for structured matrices with arbitrary rank profile

Splitting of some s-domain stability-test algorithms

A LEPSCHY, GA MIAN, U Viaro - International Journal of Control, 1989 - Taylor & Francis
Some classic s-domain algorithms are first expressed in a unified form. From this, all
possible split forms are then derived and classified. In particular, attention is focused on two …

The Lepschy stability test and its application to fractional-order systems

D Casagrande, W Krajewski, U Viaro - Archives of Control Sciences, 2021 - air.uniud.it
It is shown how a stability test, alternative to the classical Routh test, can profitably be
applied to check the presence of polynomial roots inside half-planes or even sectors of the …

Euclid-type algorithm and its applications

On the mechanism of recursive stability-test algorithms

A LEPSCHY, U Viaro - International Journal of Control, 1993 - Taylor & Francis
Most stability-test procedures are based on a recursion relation that, starting from a given
characteristic polynomial, generates a sequence of polynomials Pi (s) of descending degree …
