.TransiEnt.Basics.Blocks.FirstOrder

Information

1. Purpose of model

First order block that allows Tau=0 and has a gain implemented.

2. Level of detail, physical effects considered, and physical insight

The model was copied from ClaRa.Components.Utilities.Blocks.FirstOrderClaRa of ClaRa version 1.3.0 and y_aux was eliminated as a state for the case Tau=0. Also a gain was added, as done in Modelica.Blocks.Continuous.FirstOrder.

3. Limits of validity

(no remarks)

4. Interfaces

u: input

y: output

5. Nomenclature

(no elements)

6. Governing Equations

(no equations)

7. Remarks for Usage

evaluate_y_start = true might help avoiding circular equalities.

8. Validation

(no validation or testing necessary)

9. References
