Information

Ideal actuator motor model with hysteresis and finite actuation speed. If the current actuator position y is below (or above) the input signal u by an amount bigger than the hysteresis delta, then the position y is increased (decreased) until it reaches u. The output y is bounded between 0 and 1.

Note: This model can introduce state events which increase the computation time. For a more efficient implementation that approximates a motor, set in the valve or damper model the parameter use_inputFilter=true instead of using this motor model. See also IDEAS.Fluid.Actuators.UsersGuide.

• March 24, 2017, by Michael Wetter:
  Renamed filteredInput to use_inputFilter.
  This is for #665.
• September 8, 2008 by Michael Wetter:
  Added to instance int the attribute y(stateSelect=StateSelect.always). Without this attribute, the model IDEAS.Fluid.Examples.TwoWayValves sets y=3 which is consistent with this model.
• September 8, 2008 by Michael Wetter:
  First implementation.
