Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

This blocks computes output y (element-wise) 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.
