OPERAND DESCRIPTIONS:
Lead/lag gain - A tuning parameter that specifies the gain of the function. Lead/lag values are any
non-negative floating point number.
Lead time - A tuning parameter that specifies the lead time for the function in minutes. Lead time
values are any non-negative floating point number.
Lag time - A tuning parameter that specifies the lag time for the function in minutes. Lag time
values are any non-negative floating point number.
Reset signal - The name of the general register or discrete loadable function that contains the
reset value.
Comment - A comment up to 255 characters long.
FUNCTION EQUATIONS:
If Reset value = 0,
Then SVA(out) = [K(T
1
s + 1)/(T
2
s + 1)]SVA(in)
If Reset value = 1,
Then SVA(out) = K(SVA(IN))
SVD(out) = SVD(in)
Where: K = gain value
T
1
= time constant for lead time
T
2
= time constant for lag time
s = Laplace operator
On power up:
SVA(out) = SVA(in) X K
SVD(out) = SVD(in)
