Question
In order to stabilize the system, we use a PD controller in cascade with the feed-forward chain as shown in the following block diagram:
U(s)
1
Y(s)
K(1+s)
53+7s2-2s-15
Determine the range of K in the PD controller that makes the system stable. (K is always positive)
Select one:
O a. K> 13
O b. K>1
O C. K> 15
O d. The system is never stable
e. K>3
Given the shown circuit and its feedback block diagram, find the transfer function in the block B2. Type: a, b, c, d, e, f, g or h.
