modelSignalFilter
Partial model that implements the filtered opening for valves and dampers
Extends from Buildings.Applications.DataCenters.ChillerCooled.Equipment.BaseClasses.SignalFilterParameters (Record that contains the parameters of the filtered opening for multiple valves and dampers).
Information
Partial model that implements the filters that are used to approximate the travel time of the actuators.
The signal y_actual is used to obtain the current position of the actuators.
Parameters
| Type | Name | Default | Description |
|---|---|---|---|
| Integer | numAct (from SignalFilterParameters) | 4 | Number of filters |
| Dynamics › Time needed to open or close valve | |||
| Boolean | use_strokeTime (from SignalFilterParameters) | false | = true, if opening is filtered to avoid a step change in actuator position |
| Modelica.Units.SI.Time | strokeTime (from SignalFilterParameters) | 30 | Time needed to open or close valve |
| Modelica.Blocks.Types.Init | initValve (from SignalFilterParameters) | Modelica.Blocks.Types.Init.InitialOutput | Type of initialization (no init/steady state/initial state/initial output) |
| Real | yValve_start (from SignalFilterParameters) | fill(1, numAct) | Initial value of output:0-closed, 1-fully opened |
