Emulator Design and Generation of Synthetic Dataset in Multi-Ion Sensing

Giovanni De Micheli, Sandro Carrara, Danilo Demarchi, Mandresy Ivan Ny Hanitra

Multi-ion potentiometric sensing becomes challenging for mixed-ion samples in which interfering electrolytes significantly alter the response of each single sensor. Therefore, an emulator based on the phase-boundary potential model is proposed to simulate ...

Rotor Position Estimation with Hall-Effect Sensors in Bearingless Drives

Yves Perriard, Juan Patricio Tomás Peralta Fierro

The estimation of rotor position is fundamental for the commissioning of magnetically-levitated drives. The sensors required for this measurement must be close to the rotor, often requiring constructive measures that may limit the application potential of ...
