blockMultiSwitch
Set Integer expression that is associated with the first active input signal
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 | 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 |
| Integer | nu | 0 | Number of input connections |
Components
| Type | Name | Default | Description |

| Integer[nu] | expr | fill(0, nu) | y = if u[i] then expr[i] elseif use_pre_as_default then pre(y) else y_default |
