Step 1
The characteristic equation is given by: 1 + G(s)H(s) = 0 where G(s) is the transfer function of the system and H(s) is the transfer function of the feedback loop. In this case, the transfer function of the system is G(s) = 5 + 77s + 27s^2 + 38, and the transfer Show more…

Problem 8-10: Sketch the root locus and find the range of K for stability for the unity-feedback system shown in Figure P8.3 for the following conditions: [Section: 8.5] a. G(s) = K(s^2 + 1) / (s-1)(s+2)(s+3) b. G(s) = K(s^2 - 2s + 2) / s(s+1)(s+2) FIGURE P8.3

(a) By using the Routh-Hurwitz stability criterion, estimate the stability of the system represented by the characteristic equation: s^5 + 3s^4 + 12s^3 + 24s^2 + 32s + 48 = 0 [10] (b) The unity feedback control system is represented in Figure Q3(b): R(s) E(s) K(s+4) C(s) s(s + 1.2)(s + 2) Figure Q3(b) Evaluate the following: (i) The range of K values that keeps the system stable; [10] (ii) The value of K that makes the system oscillate; [2] (iii) The frequency of oscillation when K is set to the value that makes the system oscillate.
