s(s + 1)2 4.9 A generic negative feedback system with non-unity transfer function in the feedback path is shown in Fig. 4.5. w (a) Suppose, 1 (0.58s + 1) 1020 bm G(s) = Dc(s) = 0.42; H(s) = P. ; V(s) = 0, (0.35s + 1) SY Vizody v TORS showing a lead compensation in the feedback path. What is the eno od requirement on P such that the system will remain a Type 1 system SOLO with respect to the reference input? (b) For part (a), find the steady-state tracking error for this system to a (5) unit ramp reference input if P= 1. (c) For part (b), what is the value of the velocity error coefficient, Ky?
