Figure 7. Open Loop Frequency Response
CLOSED-LOOP SYSTEM STEP RESPONSE
a) Small - signals analysis.
The transfer function (3) can be written as follows:
(7)
where wo =
is the cutoff frequency
is the dumping factor
By choosing the
ξ value, it is possible to determine the system response to an input step signal.
Examples :
1)
ξ = 1 from which t
(where Vi is the amplitude of the input step).
2)
ξ =
