A block diagram of a closed-loop system is shown in Fig. E11.10. (a) Derive a closed-loop transfer function for disturbance changes, Y(s)!D(s). (b) For the following transfer functions, what values of Kc will result in a stable closed-loop system?

Problem 11.10A block diagram of a closed-loop system is shown in Fig. E11.10. (a) Derive a closed-looptransfer function for disturbance changes, Y(s)/D(s). (b) For the following transfer functions,what values of Kc will result in a stable closed-loop system Step-by-step solution Step 1 of 5 ^From Figure 1, the output must remain the same, while shifting a summing point. The transferfunctions of the blocks which are connected in parallel get added with each other.Reconstruct Figure 1 using shifting a summing point and blocks in parallel rule and it is shown inFigure 2.
