20.500.12556/DKUM-66367 Finite element modelling of a field-sensed magnetic suspended system for accurate proximity measurement based on a sensor fusion algorithm with Unscented Kalman Filter The presented paper describes accurate distance measurement for a field-sensed magnetic suspension system. The proximity measurement is based on a Hall effect sensor. The proximity sensor is installed directly on the lower surface of the electro-magnet, which means that it is very sensitive to external magnetic influences and disturbances. External disturbances interfere with the information signal and reduce the usability and reliability of the proximity measurements and, consequently, the whole application operation. A sensor fusion algorithm is deployed for the aforementioned reasons. The sensor fusion algorithm is based on the Unscented Kalman Filter, where a nonlinear dynamic model was derived with the Finite Element Modelling approach. The advantage of such modelling is a more accurate dynamic model parameter estimation, especially in the case when the real structure, materials and dimensions of the real-time application are known. The novelty of the paper is the design of a compact electro-magnetic actuator with a built-in low cost proximity sensor for accurate proximity measurement of the magnetic object. The paper successively presents a modelling procedure with the finite element method, design and parameter settings of a sensor fusion algorithm with Unscented Kalman Filter and, finally, the implementation procedure and results of real-time operation. accurate proximity measurement sensor fusion algorithm Unscented Kalman Filter finite element modelling meritve senzorji Unscented Kalman Filter modeliranje končnih elementov true true true Angleški jezik Slovenski jezik Znanstveno delo 2017-06-22 10:42:55 2017-06-22 10:44:26 2022-07-11 03:06:31 2019-07-11 15:45:02 2016 0 0 str. 1-23 št. 9 Letn. 16 2016 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1424-8220 681.5 10176278 19822614 10.3390/s16091504 1424-8220 URN:SI:UM:DK:2X33ZD4C Sensors_2016_Chowdhury,_Sarjas_Finite_Element_Modelling_of_a_Field-Sensed_Magnetic_Suspended_System_for_Accurate_Proximity_Measurement_B.pdf Sensors_2016_Chowdhury,_Sarjas_Finite_Element_Modelling_of_a_Field-Sensed_Magnetic_Suspended_System_for_Accurate_Proximity_Measurement_B.pdf 1 03A1C6BF1AC996B4428111BCB047F893 ca541d3cf8ff7526f71eb78e701e404d9a7c64d286f2d06ab682d9ace421df5b 480cbed6-7c0e-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=112935 http://www.mdpi.com/1424-8220/16/9/1504 1 https://dk.um.si/Dokument.php?lang=slv&id=112934 Fakulteta za elektrotehniko, računalništvo in informatiko 0 0 0
