.IBPSA.Fluid.Actuators.Valves.TwoWayEqualPercentage

Information

Two way valve with an equal percentage valve opening characteristic.

This model is based on the partial valve model IBPSA.Fluid.Actuators.BaseClasses.PartialTwoWayValve. Check this model for more information, such as the regularization near the origin.

Revisions

• April 4, 2014, by Michael Wetter:
  Moved the assignment of the flow function phi to the model instantiation because in its base class, the keyword input has been added to the variable phi.
• March 27, 2014 by Michael Wetter:
  Revised model for implementation of new valve model that computes the flow function based on a table.
• February 20, 2012 by Michael Wetter:
  Renamed parameter dp_nominal to dpValve_nominal, and added new parameter dpFixed_nominal. See IBPSA.Fluid.Actuators.UsersGuide.
• February 14, 2012 by Michael Wetter:
  Added filter to approximate the travel time of the actuator.
• March 25, 2011, by Michael Wetter:
  Added homotopy method.
• June 5, 2008 by Michael Wetter:
  First implementation.
