Extremum-seeking control of ABS braking in road vehicles with lateral force improvement
(IEEE-INST Electrical Electronics Engineers Inc, 2014-01)
An ABS control algorithm based on extremum seeking is presented in this brief. The optimum slip ratio between the tire patch and the road is searched online without having to estimate road friction conditions. This is ...
A refinement of asymptotic predictions and full numerical solution of helicopter rotor noise in the far field
(Multi-Science Publ Co Ltd, 2012-09-01)
The asymptotic analysis of Parry and Crighton [1] for propeller noise in the far field, which is based on Hanson's formulation [2] of the FW-H equation, is refined to second order by Laplace's method [3] for evaluating ...
Semianalytical solution of unsteady quasi-one-dimensional cavitating nozzle flows
(Springer, 2014-06)
Unsteady quasi-one-dimensional bubbly cavitating nozzle flows are considered by employing a homogeneous bubbly liquid flow model, where the nonlinear dynamics of cavitating bubbles is described by a modified Rayleigh-Plesset ...
Measurement and assessment of fatigue life of spot-weld joints
(Asme-Amer Soc Mechanical Eng, 2009-01)
Spot-weld joints are commonly used to fasten together metal sheets. Because fatigue fracture is the most critical failure mode for these joints under fluctuating loads, understanding their fatigue failure behavior and ...
Extremum seeking dead-zone pre-compensator for an industrial control system
(Walter De Gruyter GMBH, 2018-06-26)
PID type industrial controllers such as PI, PD, PID are mature control algorithms and they are intensively used in industry due to their simplicity and easily implementability. However, they start to fail when there is an ...
Modelling and simulation studies on adaptive controller for alt-azimuth telescopes despite unknown wind disturbance and mass
(SAGE Publications, 2020-09-15)
Numerous ground-based observatories are using small sized ground telescopes for scientific research purposes. The telescopes that are available on the market have three main problems. These issues can be listed as: positioning ...
An emergency braking controller based on extremum seeking with experimental implementation
(Springer Berlin Heidelberg, 2018-03-01)
An extremum seeking scheme is developed for maximizing the longitudinal tire forces of the road vehicles during emergency braking situations. If the road condition is known, then a conventional braking controller could ...
Frezeyle tornalamada takımda ortaya çıkan termal deformasyonların modellenmesi
(Gazi Universitesi Muhendislik-Mimarlik, 2017)
Frezeyle tornalama işleminde işlemiş parça doğruluğu ve üretkenliği arttırarak işlem performansını iyileştirmek kesme kuvvetlerini ve takım ucundaki ısı kaynaklı deformasyonları kontrol etmekle mümkündür. Bu çalışmanın ...
A thermo-mechanical model of drill margin-borehole surface interface contact conditions in dry drilling of thick CFRP laminates
(Elsevier Ltd, 2020-04-23)
Dry drilling of thick carbon fiber reinforced polymer (CFRP) laminates requires careful selection of process parameters in order to obtain acceptable borehole surface quality. Complex contact conditions between the drill ...
Computational and asymptotic methods in aeroacoustics with applications
(Işık University Press, 2011)
In this article the computational and asymptotic methods used in aeroacoustics are reviewed. In particular, two different aeroacoustic applications are demonstrated.In the first problem we investigate the first and second ...
