Q.7 The two closed loop systems shown in figure 2(a) and (b) have identical forward path and through the open loop transfer function. but differ only by the entry point of load variable into the process.
You have to check how this difference would effect the system's closed loop performance by determining
(a) offset, (b) frequency of the transient response and (c) transient response equation for a unit step of load
as disturbance with proportional controller on the loop having a gain Kc = 5.
