7.5-7. For the system of Fig. P7.5-7, T = 2s and G(₂)= K(z+0.8) (2-1)(z-0.6) (a) Determine the range of K for stability using the Routh-Hurwitz criterion. (b) Determine the range of K for stability using the Jury test. (c) Show that the upper limit of K for stability in part (a) yields a marginally stable system. (d) Show that the upper limit of K for stability in part (b) yields a marginally stable system. G(x) Fig. P7.5-7 Solution:
