Buildings.Controls.Continuous.Validation

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.

Buildings.Controls.Continuous.Validation.LimPIDReset

Test model for PID controller with optional intgerator reset

Buildings.Controls.Continuous.Validation.LimPIDReset

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).
