GradientLimiter
| GradientLimiter increments the output value y by the limited difference between consecutive input values over time Du.
The input parameters can have signs, and the condition LU ≥ LD is assumed, but not checked. |

If reset is disabled (i.e. R = FALSE) and E = TRUE, the output is buffered in the variable y as follows:
if ( ((u-y)/dT) > LU )
{
y = y+LU;
B_min = 0;
B_max = 1;
}
else if ( ((u-y)/dT) < LD )
{
y = y+LD;
B_min = 1;
B_max = 0;
}
else
{
y = u;
B_min = 0;
B_max = 0;
}
If reset is enabled (i.e. R = TRUE), the variable y is set to the initial value IV.
B_max
The value stored in B_max is returned.
B_min
The value stored in B_min is returned.
y
The value stored in y is returned.
