Abstract :
The numerical computation of the abscissa of stability of a polynomial, defined as the largest of the real parts of the zeros of the polynomial, is a problem that occurs repeatedly in computer-aided design of dynamical and control systems. The approach developed in this paper, by making repeated use of the Routh test, avoids the computation of zeros and provides a useful method.
