Vpliv viskoznosti medija na izbiro parametrov PID krmilnika pozicije magneta pri procesu magnetne levitacije

Uzunova, Zorica (author), Kozjek, Dominik (mentor)

Naraščajoča radovednost in uporaba magnetne levitacije odpirata številna še neraziskana vprašanja. Eno izmed njih je bilo, kako bi se sistem obnašal, če bi zrak zamenjali z bolj viskoznim medijem. S testiranjem PID krmiljenja pozicije lebdečega permanentnega magneta v zraku, vodi in olju smo opazovali razlike v stabilnosti, nihanju in natančnosti. Večja viskoznost se je izkazala kot dejavnik, ki poveča stabilnost in zmanjša občutljivost sistema.

Abstract

The rising curiosity and usage of magnetic levitation opens many questions yet to be explored. One of them was how the system would behave if air were replaced with a more viscous medium. By testing PID control of a levitating permanent magnet in air, water, and oil, we observed differences in stability, oscillation, and precision. Higher viscosity proved to increase system stability and reduce sensitivity to disturbances.
