Output the sum of the two inputs

Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

This blocks computes output y as sum of the two input signals u1 and u2:

y = k1*u1 + k2*u2;

Example:

   parameter:   k1= +2, k2= -3

results in the following equations:

   y = 2 * u1 - 3 * u2

Parameters (2)

k1

Value: +1

Type: Real

Description: Gain of input signal 1

k2

Value: +1

Type: Real

Description: Gain of input signal 2

u1

Type: RealInput

Description: Connector of Real input signal 1

u2

Type: RealInput
