Continuous.Integrator ​

Integrates the input signal with optional gain factor.

An integrator that computes the time integral of the input signal multiplied by a gain factor. The block implements the transfer function 1/s scaled by gain k.

Outputs y = ∫k*u dt, corresponding to the transfer function \frac{1}{s}.

This component extends from BlockComponents.Interfaces.SISO

Usage ​

BlockComponents.Continuous.Integrator(x0=0, k=1.0)

Parameters: ​

NameDescriptionUnitsDefault value
x0Initial value of the integrator state at simulation start–0
kGain factor applied to the input before integration–1.0

Connectors ​

  • u - This connector represents a real signal as an input to a component (RealInput)

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

Variables ​

NameDescriptionUnits
xInternal state variable that stores the integrated value–

Integrates the input signal with optional gain factor.

An integrator that computes the time integral of the input signal multiplied by a gain factor.
The block implements the transfer function 1/s scaled by gain k.

```math
y(t) = \int_{t_0}^{t} k \cdot u(\tau) d\tau + x_0
