Add

Weighted adder that outputs the sum of two scalar inputs with configurable gains.

Combines two input signals by multiplying each by its respective gain parameter and adding the results. The output is calculated as

$$y=k1\cdot u1+k2\cdot u2$$

where k1 and k2 are configurable gain factors that determine the weight of each input in the sum.

This component extends from SI2SO

Usage

BlockComponents.Add(k1=1.0, k2=1.0)

Parameters:

Name	Description	Units	Default value
k1	Gain multiplier for the first input (u1)	–	1
k2	Gain multiplier for the second input (u2)	–	1

Connectors

• u1 - This connector represents a real signal as an input to a component (RealInput)

• u2 - This connector represents a real signal as an input to a component (RealInput)

• y - This connector represents a real signal as an output from a component (RealOutput)

Behavior

$$\begin{array}{rl}y\left(t\right)& =\mathtt{k}\mathtt{1}\mathtt{u}\mathtt{1}\left(t\right)+\mathtt{k}\mathtt{2}\mathtt{u}\mathtt{2}\left(t\right)\end{array}$$
