Short description of the block

1. Purpose of Block

description of typical application cases

2. Limits of Validity / Features

anti-windup compensation
input/output filtering → no low pass filter for inlet or outlet
usage of relative variable for the PI core → units are expected to be in p.u.
smooth transitions from manual mode to control mode
allows delayed activation of the controller, a constant value is output before activation
variable max/min outputs with smooth behaviour during change
variable control parameters
options to block positive and negative transitions
avoid events as possible
flexible and easy to understand initialisation
bus-like feedback from downstream variables
- gradient of output is limited by downstream variable
- max/min limit of downstream variable is reached
PI and I-Endlagenverhalten
"Blitznachlauf"

4. Nomenclature

a table referencing the nomenclature in the source code, the descriptions of variables and the "human-readable" , use the following latex table template:
\begin{tabular}{||l|l||l||l|}
\hline SourceCode & Variable ClaRaCCS & Variable name from [1]& Description\\\hline\hline
\texttt{Delta\_h\_vap} & $\Delta h_vap$ &$L_v$ & Heat of vapourisation \\\hline
\end{tabular}
