A phase-locked loop (PLL) is a nonlinear negative-feedback control system that
synchronizes its output in frequency as well as in phase with its input. PLLs are now widely …

Optical and magnetic linear/rotary encoders are well-known systems traditionally used in
industry for the accurate measurement of linear/angular displacements and velocities …

A self‐powered, sliding electrification based quasi‐static triboelectric sensor (QS‐TES) for
detecting angle from rotating motion is reported. This innovative, cost‐effective, simply …

To measure the angular position of motors, robot joints, etc., an absolute magnetic rotary
position sensor is developed, which possesses small-size, light, robust, and easy-to …

Based on the law of electromagnetic induction, a novel contactless absolute angular
position sensor has been designed in the literature. It is mainly composed of three parts: two …

A novel design of a magnetic rotational sensor is presented in this paper. It contains a ring
magnet simply magnetized through its central axis, which is deliberately displaced a …

Triboelectric motion sensors, based on the generation of a voltage across two dissimilar
materials sliding across each other as a result of the triboelectric effect, have generated …

Absolute magnetic encoders (AMEs) use two magnets: a ring multipolar magnet (MPM)
generating high-resolution and improving the accuracy for the encoder, and a bipolar …

This paper presents a novel algorithm based on polynomial approximations (PAs) for an
efficient error compensation of magnetic analog encoders (MAEs) in permanent-magnet …

This paper proposes a method to improve the accuracy of an absolute magnetic encoder by
using harmonic rejection (HR) and a dual-phase-locked loop (DPLL). The encoder consists …
