.BuildingSystems.Utilities.Math.IntegratorWithReset

Information

This model is similar to Modelica.Blocks.Continuous.Integrator except that it optionally allows to reset the output y of the integrator.

The output of the integrator can be reset as follows:

• If reset = BuildingSystems.Types.Reset.Disabled, which is the default, then the integrator is never reset.
• If reset = BuildingSystems.Types.Reset.Parameter, then a boolean input signal trigger is enabled. Whenever the value of this input changes from false to true, the integrator is reset by setting y to the value of the parameter y_reset.
• If reset = BuildingSystems.Types.Reset.Input, then a boolean input signal trigger is enabled. Whenever the value of this input changes from false to true, the integrator is reset by setting y to the value of the input signal y_reset_in.

See BuildingSystems.Utilities.Math.Examples.IntegratorWithReset for an example.

Implementation

To adjust the icon layer, the code of Modelica.Blocks.Continuous.Integrator has been copied into this model rather than extended.

  Corrected wrong annotation for y_reset, and made rendering of y_reset_in conditional.
  This is for #562.

  Refactored model to use a type for configuration of the integrator reset.
