Human Perception-Based Washout Filtering Using Genetic Algorithm
2015The Motion Cueing Algorithm MCA transforms longitudinal and rotational motions into simulator movement, aiming to regenerate high fidelity motion within the simulators physical limitations. Classical washout filters are widely used in commercial simulators because of their relative simplicity and reasonable performance.

Washout of Grains from Filtered Sand and Gravel Materials
Journal of Geotechnical Engineering, 1993Some presently used filter criteria are illogical. Besides satisfying D15/d85≤5 and D15/d15≥4, both the base and filter materials must possess grading stability when exposed to seepage. There are two reasons for grading instability; scantiness of intermediate grain sizes, which interrupts an internal filter formation process; and loose grains, which ...

Adaptive motion washout filter design by using self-tuning fuzzy control
2009 IEEE/ASME International Conference on Advanced Intelligent Mechatronics, 2009The purpose of this research is to improve the motion-cueing fidelity of the simulator by using fuzzy-tuning technique to tune the parameters of washout filter in real-time.

Washout Filters in the Bifurcation Control of High Alpha Flight Dynamics
1991 American Control Conference, 1991Washout filters are employed in the design of stabilizing controllers for systems undergoing bifurcations. Moreover, the advantages of using washout filters are demonstrated in the control of a high angle-of-attack nonlinear aircraft model. In the bifurcation control of an F-8 model in [2], the performance of the controller depended on a priori ...

Increasing Motion Fidelity in Driving Simulators Using a Fuzzy-Based Washout Filter
IEEE Transactions on Intelligent Vehicles, 2019The motion cueing algorithm is the procedure used to regenerate vehicle motion cues by transforming translational and rotational motions of a simulated vehicle into the simulator motion such that high fidelity motions can be generated through a washout filter.

A Particle Swarm Optimization-based washout filter for improving simulator motion fidelity
2016 IEEE International Conference on Systems, Man, and Cybernetics (SMC), 2016The washout filter for a driving simulator is able to regenerate high fidelity vehicle translational and rotational motions within the simulator's physical limitations and return the simulator platform back to its initial position. The classical washout filter provides a popular solution that has been broadly utilized in different commercial simulators

Model based fault diagnosis for drillstring washout using iterated unscented Kalman filter
Journal of Petroleum Science and Engineering, 2019Abstract In this study, a model based fault diagnosis method for drillstring washout is proposed, which uses iterated unscented Kalman filter (IUKF) to detect the emergence of drillstring washout and to estimate washout depth and washout rate. To quantify the changes in pressure-loss and annulus outlet flow rate resulting from drillstring washout ...

Chaotic synchronization of a fractional-order system based on washout filter control
Communications in Nonlinear Science and Numerical Simulation, 2011Abstract In this paper, chaos in a fractional-order neural network system with varying time delays is presented, and chaotic synchronization system with varying time delays is constructed. The stability of constructed synchronization system is analyzed by Laplace transformation theory.

Anti-control of Hopf bifurcation for Chen's system through washout filters
Neurocomputing, 2010In this paper, we consider the problem of anti-controlling bifurcations for Chen's system, that is, a certain bifurcation is created at a desired location with preferred properties by appropriate control. Washout-filter-aided dynamic feedback control laws are developed for the creation of Hopf bifurcations. By choosing appropriate control parameter, we

An Optimal Washout Filter Design with Fuzzy Compensation for a Motion Platform
IFAC Proceedings Volumes, 2011Abstract The realistic motion of the vehicular simulator is produced by the motion cueing algorithm. An optimal washout filter, taking into account the limitation of the simulator's workspace, is applied here to minimize human's perception error in order to provide realistic behavior.
