Modelica_StateGraph2.Blocks.MathReal.MultiSwitch

Information

The block has a vector of Boolean input signals u[nu] and a vector of (time varying) Real expressions expr[:]. The output signal y is set to expr[i], if i is the first element in the input vector u that is true. If all input signals are false, y is set to parameter "y_default":

  // Conceptual equation (not valid Modelica)
  i = 'first element of u[:] that is true';
  y = if i==0 then y_default else expr[i];

Parameters

Type	Name	Default	Description
Real	expr[nu]	fill(0.0, nu)	y = if u[i] then expr[i] else y_default (time varying)
Real	y_default	0.0	Default value of output y if all u[i] = false
Advanced
Integer	precision	3	Number of significant digits to be shown in dynamic diagram layer for y

Connectors

Type	Name	Description
input BooleanVectorInput	u[nu]	Set y = expr[i], if u[i] = true
output RealOutput	y	Output depending on expression
