and settling
Please note that t r
is time calculated from 10% to 90% of output signals and t s
is the time in
witch the system transient decay to +-1%.
Figure 5.29. The relationship between overshoot, rise time and settling time versus
amplitude control loop.
From a few values of
C Ψ d
=[0.4046, 0.2688, 0.1720] we can selected C Ψ d
guaranties overshoot 0% and settling time about 10 samples.
