Unformatted text preview: The asymptote realaxis intercept is The asymptote angles are There are n m = 2 distinct asymptotes with angles The closedloop characteristic equation is The Routh table is . Since z lag > p lag , there are two sign changes in the first column and, thus, there are two poles in the right half plane for all values of K and the closedloop system will always be unstable. The Root Locus Diagram is given below. Compensators-2.5-2-1.5-1-0.5 0.5-8-6-4-2 2 4 6 8 Real Axis Imaginary Axis...
