response.
About PV filter time constant
This is a filter function on the software, which has the same effect as a CR
filter. By calculating first-order lag of PV, this suppresses input fluctuation
caused by noise.
When the input value changes as shown in (Fig. 8.5-2), this function makes
the input change slow as shown in (Fig. 8.5-3).
T (PV filter time constant) is the time when input change reaches 63% of the
desired PV.
