Buildings.Controls.OBC.CDL.Routing.RealExtractSignal

Extract signals from an input signal vector

Buildings.Controls.OBC.CDL.Routing.RealExtractSignal

Information

Extract signals from the input connector and transfer them to the output connector.

The extracting scheme is given by the integer vector extract. This vector specifies which input signals are taken and in which order they are transferred to the output vector. Note that the dimension of extract has to match the number of outputs. Additionally, the dimensions of the input connector signals and the output connector signals have to be explicitly defined via the parameters nin and nout.

Example

The specification

     nin = 7 "Number of inputs";
     nout = 4 "Number of outputs";
     extract[nout] = {6,3,3,2} "Extracting vector";

extracts four output signals (nout=4) from the seven elements of the input vector (nin=7):

   output no. 1 is set equal to input no. 6
   output no. 2 is set equal to input no. 3
   output no. 3 is set equal to input no. 3
   output no. 4 is set equal to input no. 2

Parameters

Type	Name	Default	Description
Integer	nin	1	Number of inputs
Integer	nout	1	Number of outputs
Integer	extract[nout]	1:nout	Extracting vector

Connectors

Type	Name	Description
input RealInput	u[nin]	Connector of Real input signal
output RealOutput	y[nout]	Connector of Real output signal
