Collection of validation models
Information
This package contains validation models for the classes in
Buildings.Controls.Continuous.
Note that most validation models contain simple input data
which may not be realistic, but for which the correct
output can be obtained through an analytic solution.
The examples plot various outputs, which have been verified against these
solutions. These model outputs are stored as reference data and
used for continuous validation whenever models in the library change.

Test model for PID controller with optional intgerator reset |
Test model for PID controller with optional intgerator reset
Information
This model tests the implementation the
Buildings.Controls.Continuous.LimPID
with integrator reset.
The instance limPIOri is the original implementation of the controller
from the Modelica Standard Library.
The instance limPIWithReset is the implementation from this library
with integrator reset enabled. Whenever the boolean pulse input becomes true,
the integrator is reset to y_reset.
Extends from Modelica.Icons.Example (Icon for runnable examples).
