16.7. (a) For the control system shown in Fig. P16-7, determine the transfer function C/U. (b) For K-2 and to =1, find C(1.25) and the offset if U(t) = u(t), a unit step. (c) Sketch the open-loop Bode diagram for K = 2 and tp = 1. For the upper part of the diagram (AR versus ), show the asymptotic approximation. Include the transfer func- tion for the controller in the open-loop Bode diagram. (d) From the Bode diagram, what do you conclude about the stability of the closed-loop system? FIGURE P16-7 K(1+8)
