.AixLib.Fluid.BaseClasses.ActuatorFilter

Information

This block implements a filter that is used to approximate the actuators of valves, dampers and fans.

Implementation

The implementation is based on Modelica.Blocks.Continuous.CriticalDamping. It differs from that model in that the internal state of the filter s is transformed using x = u_nominal*s. It turns out that this transformation leads to smaller system of nonlinear equations if u_nominal ≠ 0, see IBPSA, #1498 for a discussion.
