Suppose you are given a first order system whose transfer function is HP(s) = KP/(TP*s + 1).
Now, you want to control this system using a standard P (proportional) controller whose transfer function is HR(s) = KR (a proportionality coefficient).
There is also disturbance that acts upon this system and the system in analyzed in closed-loop (feed-back loop).
If you calculate the closed-loop transfer function, H0(s) = (KR*KP)/(TP*s + 1 + KR*KP ).
I am also given the transfer function in relation to the disturbance, which is H0v(s) = (KP)/(TP*s + 1 + KR*KP ), but I don't understand how this is calculated.
This is the system:
The question is: how do I calculate the transfer function in relation to the disturbance?
Thanks!
