Transfer function is ω(s)/V (s) = Km RaJs2 +KbKms+KmKKt. With v(t) = t, we have V (s) = 1/s2, and Td(s) = 0. Using the final value theorem yields ess = lim s→0 sE(s) = lim s→0 1 s+ KKmRaJs+KmKb = Kb K = 0.1 K. We desire that ess = 0.1 K 1. For example, we can take K = 8.

150 CHAPTER 4 Feedback Control System Characteristics (b) The closed-loop transfer function is Y (s) R(s) = K s3 + 4s2 + 4s +K. The steady-state error (when R(s) = 1/s2) is ess = lim s→0 s(1− T (s)) 1 s2 = lim s→0 s3 + 4s2 + 4s s(s3 + 4s2 + 4s+K) = 4 K. (c) Let K = 8. Then, Y (s) Td(s) = −s s3 + 4s2 + 4s+ 8.

Advanced Problems 151 (b) The system sensitivity is defined as SGC = ∂G/G ∂C/C. Therefore, the sensitivity is determined to be SGC = RCs (2 +RCs)(1 +RCs) = 1( 1 + 2RCs ) ( 1 + 1RCs ). (c) Let V (s) = 1/s.

Then Vo(s) = 1 +RCs 2 +RCs 1 s = 0.5 s + 0.5RC RCs+ 2. Taking the inverse Laplace transform yields vo(t) = 0.5(1 + e −2t/RC )u(t) where u(t) is the unit step function. A plot of vo(t) versus t/RC is shown in Figure AP4.6. 0.5 0.55 0.6 0.65 0.7 0.75 0.8 0.85 0.9 0.95 1 0 0.5 1 1.5 2 2.5 3 3.5 4 4.5 5 t / RC Vo FIGURE AP4.6 Step response.

(b) The transfer function from N(s) to Y (s) is Y (s) N(s) = 2K s(s+ 2) + 2K. (c) Let Td(s) = A/s and N(s) = B/s.

Then, ess = −yss = lim s→0 s −2s s(s+ 2) + 2K A s + lim s→0 s −2K s(s+ 2) + 2K B s = −B. So, K has no effect on the steady-state errors.

However, choosing K = 100 will minimize the effects of the disturbance Td(s) during the transient period. AP4.8 (a) The closed-loop transfer function is T (s) = Kb s+Kb+ 1. (b) The sensitivity is determined to be STb = ∂T/T ∂b/b = s+ 1 s+Kb+ 1.

(c) The transfer function from Td(s) to Y (s) is Y (s) Td(s) = b s+Kb+ 1. So, choose K as large as possible, to make Y (s)/Td(s) as “small” as possible.

Thus, select K = 50. This also minimizes STb at low frequencies. Solutions Manual to Accompany Modern Control Systems, Eleventh Edition, by Richard C Dorf and Robert H. ISBN-13: 298.
