Modelica_StateGraph2.Blocks.MathInteger.MultiSwitch

Information

The block has a vector of Boolean input signals u[nu] and a vector of (time varying) Integer 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" or to pre(y) depending on the parameter use_pre_as_default:

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

Parameters

Type	Name	Default	Description
Integer	expr[nu]	fill(0, nu)	y = if u[i] then expr[i] elseif use_pre_as_default then pre(y) else y_default
Integer	y_default	0	Default value of output y if use_pre_as_default=false, as well as pre(y) at initial time
Boolean	use_pre_as_default	true	= true, y holds its last value if all u[i]=false, otherwise y=y_default

Connectors

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