Limitations of routh criterion
Nettet27. apr. 2024 · Intersection of the root locus with the imaginary axis: The point at which the locus crosses the imaginary axis, in case it does, is determined by applying the Routh-Hurwitz criterion. The value of K for which the locus crosses the imaginary axis is calculated by equating the terms in the first column of the Routh array of s 1 and s 0 to … Nettet24. okt. 2008 · In this paper a direct proof of the Routh-Hurwitz conditions themselves is given using Liapunov's second method. The new proof is ‘elementary’ in that it depends on the fundamental concept of stability associated with Liapunov's second method, and not on theorems in the complex integral calculus which are required in the usual proofs.
