Question: For the unity feedback system shown in Figure 8.3, where do the following: [Section: 8.7] a. Find the gain, K, to yield a 1-second peak

For the unity feedback system shown in Figure 8.3, where

K(s? + 4s +5) G(s) = (s2 + 2s+5)(s + 3)(s +4)

do the following: [Section: 8.7]

a. Find the gain, K, to yield a 1-second peak time if one assumes a second-order approximation.

b. Check the accuracy of the second-order approximation using MATLAB to simulate the system.

K(s? + 4s +5) G(s) = (s2 + 2s+5)(s + 3)(s +4)
