C(c) Problem 5. For each of the second order transfer function given below, where G(s) = R(s) (a) Find the locations of the poles, natural frequeney and damping ratio values. (b) Determine the forms (undamped, etc.) and write the general expressions of the unit step responses. (c) Find the steady-state, c, and peak values, cmar, of the responses (depending on the forms of the responses, you may use the formulas at the bottom of the page). (d) Revise each transfer function to produce unit step responses approximately two times slower in terms of the settling time while maintaining the same forms and steady-state values. (e) Plot each response pairs (the original and its slower version) on the same plane as seen in the example below. 12 29 522 (i) G, (s) = (ii) G2(s) = (iii) G3 (s) = (s+2)(s+8)* s2+65+58 * s3+24s2+166s+1044 54 24(s+20) (iv) G4(s) (v) G3(s) s2+12s+36 (s+4) (s+24) PS.
