Please show the process on how you got the answer.

CHALLENGE: You are now given a problem to test your knowledge of this chapter's objectives. You are given the antenna azimuth position control system shown on the front endpapers, Configuration $2.$ In the challenge in Chapter $8,$ you were asked to design, via gain adjustment, an $8-$second settling time.

a$.$ For your solution to the challenge in Chapter $8,$ evaluate the percent overshoot and the value of the appropriate static error constant.

b$.$ Design a cascade compensator to reduce the percent overshoot by a factor of $4$ and the settling time by a factor of $2.$ Also, improve the appropriate static error constant by a factor of $2.$

c$.$ Repeat Part b using MATLAB $.$

I obtained a K value of $9\mathrm{.}11$ in the challenge in chapter $8.$ I used the block diagram parameters with configuration $2.$
