– is the time required for step response to reach its first peak.
4. Settling time, t
s
– is the time required for the step response to reach a ±5% band
around the final value and remain within that band thereafter.
5. Maximum (percentage) overshoot, M
p
– is the difference between the maximum
peak value attained by the step response and the final value of step response
expressed as a fraction or percentage of the final value of step response.
These measures are illustrated on a typical step response plot of a series RLCcircuit
(capacitor voltage is plotted) in the Fig. 11.9-1.
It is possible to derive expressions for these measures starting ...
