20.6.4.3. Integrator

The Integrator block outputs the integral of the input signal at the current simulation time step. CoLink uses a number of different numerical integration methods to compute

\(y(t)=\int{_{t_0}^{t}} u(t) dt +y_0\)

The user can select a numerical integration method in the Simulation Parameter Menu.

Table 20.33 Parameters

Parameter(s)	Description
Initial condition	If Initial condition source parameter is set to internal, the block gets the initial conditions from this parameter.
Abs tolerance	Enter the value for the Absolute tolerance. If the Abs tolerance is inputted as -1, the value defined in the Simulation Parameter dialog box is used. If the Abs tolerance is inputted as a value, this value is used instead of the value defined in the Simulation Parameter dialog box.
