Lоng Questiоn 1 (Tоtаl 20 points) START ON A NEW PAGE. Work in а neаt, clean, and organized way (and get extra credit!) Type the answer below Briefly show your page(s) to the camera during the exam for academic integrity. You'll submit your written work as a pdf after the exam is over. Consider a feedback system below with G = 2/(s+2). You want to design a controller K(s) to meet all the following specifications below. If r = 1 (i.e. a step), then the y(t) should reach the same value 1 in the steady state, i.e., zero error for step r. the settling time of y(t) response should be less than 8 seconds. the overshoot of y(t) response should be less than 5%. Answer the following parts neatly and separately: What do you need from/in the controller K(s) to meet the first specification (steady state y = r)? Explain briefly and mathematically. (3 points) Draw the region in the 2D complex plane where the closed loop poles should be so that the settling time and overshoot specifications above are met? Explain briefly and mathematically. (5 points) By plotting the root locus explain what type of controller is needed to meet all the specifications.i.e., what controller poles and zeros (if any) are needed to meet all the specifications. (6 points) Perform the calculations to find your final controller transfer function K(s), i.e. find the numerical values of gain/pole/zeros of K(s) to get the transfer function. (6 points) Type the final answer TF below.
