Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
This blocks computes output y as integral of the input u multiplied with the gain k:
k
y = - u
s
It might be difficult to initialize the integrator in steady state. This is discussed in the description of package Continuous.
If the reset port is enabled, then the output y is reset to set or to y_start (if the set port is not enabled), whenever the reset port has a rising edge.
