Q-2 Consider the servo system with tachometer feedback shown in Fig.Q-2, below.. (a) Compare the block diagram of Q-2 with that of Q-1, assuming no disturbance, and determine the values for K, Kh, B, and J (with their proper units).[20 pts.] (b) Determine the transfer function of the system with a step disturbance.[15 pts] (c) Also obtain the steady-state error when the system is subjected to a reference (unit-ramp) input and a disturbance (step input of magnitude d.) [15 pts.] (d) Determine the value of d that will result with zero steady-state error. [08 pts.]

Step 1
Q-2. The system has a reference input R(s), an error signal E(s), a controller gain K, a disturbance input D(s), a plant transfer function 1/(Js+B), a position output C(s), and a tachometer feedback with gain Kh. Show more…

Consider the servo system with tachometer feedback shown in Figure 5-81. Determine the ranges of stability for K and Kh. (Note that Kh must be positive.) (Sketch the stable region in the K Kh plane) Figure 5-81: Servo system with tachometer feedback. From the block diagram of Figure 5-81, we have C(s)/R(s) = 20K / (s^3 + 5s^2 + (4 + 20K Kh)s + 20K)
Prob 5 | A standard feedback control block diagram is shown in the figure below with the values G(s) = 1/s, D(s) = 2(s + 1)/s, H(s) = 100/(s + 100) a) Let W = V = 0 and compute the transfer function from R -> Y b) Let R = V = 0 and compute the transfer function from W -> Y c) What is the steady-state tracking error E if R is a unit step input (r(t) = 1, t > 0 and r(t) = 0, t < 0) and W = 0? d) What is the steady-state tracking error E if R is a unit ramp input (r(t) = t, t > 0 and r(t) = 0, t < 0) and W = 0?
