Project management and status update for DAG (Eastern Anatolia Observatory) the 4 meter VIS/IR optical telescope
(SPIE-Int Soc Optical Engineering, 2018)
The new 4 m Turkish telescope, DAG (East Anatolian Observatory, Fig. 2), will be located on the summit of the mountain Konakli-Karakaya, at an altitude of 3170 m, near the city of Erzurum, Turkey. First light is expected ...
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 ...
A flexible adaptive optics concept for general purpose high angular resolution science on the DAG 4m telescope
(SPIE-Int Soc Optical Engineering, 2018)
Thanks to the availability of high actuator density deformable mirrors (ALPAO 468 DM), the high versatility of the pyramid wavefront sensor and above all, the venue of essentially no noise EMCCD detectors, it becomes ...
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 ...
