20.500.12556/RUL-186575 Izbira senzorja položaja magneta za sistem magnetne levitacije in preizkus delovanja izbranega senzorja The selection of a magnet position sensor for a magnetic levitation system and test of the chosen sensor Magnetna levitacija je pojav, ki omogoča lebdenje predmetov brez fizičnega stika. V sistemih magnetne levitacije je za doseganje želenega položaja magneta potrebno sprotno merjenje položaja magneta, kar predstavlja glavni vhodni signal za krmilni algoritem. V okviru tega dela smo pregledali trg za izbiro primernega senzorskega elementa, s katerim bi za doseganje bolj zanesljivega merjenja položaja magneta lahko nadomestili par Hallovih senzorjev v že vzpostavljenem demonstracijskem sistemu magnetne levitacije. Primerjali smo uporabljen par Hallovih senzorjev, ultrazvočni senzor, LIDAR in linijski optični senzor. Za dejansko implementacijo smo izbrali linijski optični senzor, ker ima visoko frekvenco merjenja in primerno nizko ceno. Senzor smo implementirali, umerili in ovrednotili. Magnetic levitation is a phenomenon that enables objects to float without physical contact. In magnetic levitation systems, continuous measurement of the magnet's position is required to achieve the desired position, as it provides the primary input signal for the control algorithm. In this work, a market survey was conducted to identify a suitable sensing element capable of replacing the pair of Hall sensors in an existing magnetic levitation demonstration system, thereby improving the reliability of position measurement. The existing pair of Hall sensors, an ultrasonic sensor, a LIDAR sensor, and a linear optical sensor were compared. Based on its high sampling rate and reasonable cost, the linear optical sensor was selected for implementation. The sensor was implemented, calibrated, and its performance was evaluated. magnetna levitacija merjenje položaja magneta brezkontaktno merjenje meritve in situ v realnem času linijski optični senzor CMOS magnetic levitation magnet position measurement contactless measurement real-time in situ measurement linear image sensor CMOS true false false [B.
