Name_________________________
Let's assume that you have a system with the usual feedback configuration
as shown below.
The transfer function
of the controlled system, G(s), is given by:
G(s) = 7/(s + 3)
-
Determine the closed loop
DC gain when the proportional controller gain, Kp, is
10.
-
Determine the sensitivity
of the closed loop time constant to changes in the DC gain of G(s).
-
Using the sensitivity,
estimate the change in the closed loop time constant when the DC gain of
G(s) increases by 10%.
