SETIAHO 17.1. (a) Obtain Gf for the feedforward-feedback system shown in Fig. P17-1 so that C does not change when a disturbance in C; occurs. Would there be any problem in implementing this Gf? (b) If Gris to be a lead-lag transfer function Tis + 1 T2s +1 AMMUZ HIULIA determine T, and T2 by the Foxboro rule. How do you determine whether lead or lag is to predominate? Use tp = 1.0 in the Foxboro rule. (c) When feedforward-feedback control is present, sketch the response C(t) when C; = 1/s and when Gf from part (a) is used. () colo ) Repean parte con whene Ge from part (6) is used. Only a rough sketch that transient response is expected in this case. (e) Determine C(t) when C; = 1/s, Gy = -1, and the feedback loop is broken at A-A. SH 100g Obtain the numerical value of C(t) at t = 0.5, 1.0, and 1.5. sketch that suggests the 152 DO onda 1 sm 1 co Rino Ci= lombo S + 1 Gif HOSPI De to podiet andere ar 7039 + ++ + Berts 1 R=0-> K=1 (s + 1)2 A 10 HAWAON FIGURE P17-1100 Xosdossi iste natanud noo ni baat vlintse a lines fra trebao Til erit mihi bad 21 2359014 al lo lsbom A nois sound mulb 1 no somed
