Constant ​

Provides a constant output signal of value k.

Generates a constant signal that doesn't change over time. The output y is always equal to the parameter k, regardless of simulation time or system state. This is often used as a reference signal, bias term, or fixed input to other components in a control system or simulation.

This component extends from SO

Usage ​

BlockComponents.Constant(k)

Parameters: ​

NameDescriptionUnitsDefault value
kThe constant value to output–

Connectors ​

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

Behavior ​

y(t)=k
