The Routh-Hurwitz criterion 2 Consider a polynomial p(s)=ansn+an−1sn−1+···+a0. (1) The first two rows of the Routh array are obtained by copying the coefficients of p(s)using the pattern shown below. sn sn−1 sn−2 n an an−2 an−4 an−6 ··· a −1 a n3 a 5 ··· ··· x1 x2 x3 ··· ··· When a0 is reached in one of the first two rows, blanks are left in the remaining The Routh array is a tabular method permitting one to establish the stability of a system using only the coefficients of the characteristic polynomial. Central to the field of control systems design, the Routh-Hurwitz theorem and Routh array emerge by using the Euclidean algorithm and Sturm's theorem in evaluating Cauchy indices . A partir de la función de transferencia Ecuación 16.3.8 se pretende agilizar tanto la evaluación por los criterios de Routh siguiente como mediante un análisis más general de estabilidad en Sección, encontramos la ecuación característica: Den(p) ≡ a1p3 + a2p2 + a3p + a4 = p3 + ( 1 τL + cθ J)p2 + cθ J 1 τLp + KaKθ JτL = 0.

Reviews (57) Discussions (23) Routh-Hurwitz stability criterion identifies the conditions when the poles of a polynomial cross into the right. hand half plane and hence would be considered as unstable in control engineering. In most undergraduate texts on control systems, the Routh-Hurwitz criterion is usually introduced as a mechanical algorithm for determining the Hurwitz stability of a real polynomial. Unlike many other stability criteria, such as the Nyquist criterion, root locus, etc., no attempt whatsoever is made to even allude to a proof of the Routh-Hurwitz criterion.
