a. A closed-loop system has a hold circuit and process as shown below. Determine G(z) when T = 1 and Go(s) = 2/(s + 2) r(t) + y(t) Zero-order hold Go(s) Process G₂(s) b. A sampled-data system such as that presented in problem (i) has a sampling period T = 0.05s and has G(z) = K (z³ + 10.3614z² +9.758z + 0.8353) / (z4 - 3.7123z³ + 5.1644z² - 3.195z + 0.7408) Determine K when the two real poles break away from the real axis. Calculate the maximum K for stability.
