For the block diagram shown below, (1) draw the equivalent signal flow graph of the system, (2) find E(s)/R(s), and (3) find C(s)/R(s). (15 points) GA G1 G G3 H2 2. For the two feedback systems shown below, (a) Find the closed-loop transfer functions T1 and T2 for each system, (b) Show that T1 = T2 = 100 when Ki = K2 = 100, and (c) Compare the sensitivities of the two systems with respect to the parameter K1 for the nominal values of K1 = K2 = 100. (20 points) T. = Ville R(S) K C (s) 1- 009 9 4, MZ (1) 0.0099 -.09 R(S) K1 K2 c(s ) 1 +. 094, + , 09 *2 + , 60814 , 42 L. =09 k. 0.09 ( 100 ) ( 100) 0.09 LZ =- 09 k z 1 +. 09 ( 160 ) (2) 4 = 1 -(-,0941 - 0942 ) +.008 *. 1/2 3. For a unity feedback control system with controller Gc(s) = K and plant Gp(s) = 1/[s(s+K1)], (a) calculate the sensitivity of the closed-loop transfer function to changes in K1, and (b) how would you select a value for K to minimize the effects of K1 variation. (10 points) 4. Construct the signal flow graph for the following set of simultaneous equations: X2 = A21 X1 + A23 X3, X3 = A31 X1 + A32 X2 + A33 X3, X4 = A42X2 + A43X3. Identify the (a) input node, (b) output node, (c) forward paths, (d) feedback paths, and (e) self-loop. (15 points)...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
