In signal processing, a washout filter is a filter that makes a transition caused by changes in the input source more smooth. An example of this transition is the change in the modes of a signal. The function of a filter like this, is to damp the DC part of a signal which is most useful . A washout filter is a high pass filter that washes out (rejects) steady state inputs, while passing transient inputs. Feedback through washout filters does not move the equilibrium points of the open-loop system.
Moreover, the limitations of delayed feedback control can be overcome by the use of washout filter -aided feedback, which gives rise to the possibility of stabilizing a much larger class of systems.

The washout filter places a zero at the origin, which constrains the spiral mode pole . Limitations and Extensions. Chung Shan Institute of . Abstract: Advantages and limitations of washout filters in feedback control of both continuous-time and discrete-time systems are discusse and generalizations that alleviate the limitations are presented. The generalized washout filters presented involve feedback through auxiliary state variables that are intercoupled.
My motion platform sloping limitation is ± degrees maximum in one DOF at a time without vertical displacement. Vertical displacement limitation is ± 16. In this paper, we propose a new approach which is based on human vestibular system and motion platform limitation for designing washout filter such that a cost function constraining the pilot sensation error (between simulator and vehicle) is minimized.
Finally, the experimental confirm the effectiveness of our . The method involves incorporation of filters called washout filters into the controller architecture. A washout filter -aided control law preserves all system equilibria, and does so without the need for an accurate system model. The realistic motion of the vehicular simulator is produced by the motion cueing algorithm.

Specifically, we have incorporated high pass filters known as washout filters into the structure of the allowed controllers. In this way, we guarantee preservation of all system equilibria even under model uncertainty. Note that washout filters are common in power system stabilizers and aircraft control systems.
