Obtain Gy for the feedforward-feedback system shown in Fig. so that C does not change when a disturbance in C, occurs. Would there be any problem in implementing this G If Gy is to be a lead-lag transfer function G==--- determine T and T by the Foxboro rule. How do you determine whether lead or lag is to predominate? Use tp = 1.0 in the Foxboro rule. When feedforward-feedback control is present, sketch the response C(t) when C = 1/s and when Gy from part (a) is used. Repeat part (c) when Gy from part (b) is used. Only a rough sketch that suggests the transient response is expected in this case. Determine C(1) when C = 1/s, Gy=-1, and the feedback loop is broken at A-A. Obtain the numerical value of C(t) at t = 0.5, 1.0, and 1.5. R=0-> Co Gf Ts +1 Ts + 1 200 K = 1 (s + 1)
