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.
The filter order can be changed to modify the transient response of the actuator.
See IBPSA.Fluid.Actuators.UsersGuide for a description of the filter.
