Laplace.T Root-locus Transient response Frecuency response

4 Program 6.5 OGATA 4edition (root locus, damping ratios, undamped natural frecuency)

We will draw polar grids in root-locus by a Scilab with the damping ratios $\zeta$=0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9 and undamped natural frecuency $\omega_{n}$=1,2.
