modelActuatorSignal

Partial model that implements the filtered opening for valves and dampers

Information

This model implements the filter that is used to approximate the travel time of the actuator. Models that extend this model use the signal y_actual to obtain the current position of the actuator.

See Annex60.Fluid.Actuators.UsersGuide for a description of the filter.
