  1. 41. Estimation and Compensation of Load-Dependent Position Error in a Hybrid Stepper Motor

    University essay from Linköpings universitet/Reglerteknik

    Author : Anton Ronquist; Birger Winroth; [2016]
    Keywords : Adaptive Notch Filter; Back-EMF; Electric Motor Position Control; Error Modelling; Field-Oriented Control; Hybrid Stepper Motor; Kalman Filter; Load Angle; Magnetic Rotary Position Sensor; Sensorless Control; Sliding Window Discrete Fourier Transform; Stall Detection and Prediction.;

    Abstract : Hybrid stepper motors are a common type of electric motor used throughout industry thanks to its low-cost, high torque at low speed and open loop positioning capabilities. However, a closed loop control is often required for industrial applications with high precision requirements. READ MORE

  3. 42. Torque Sensor for Automotive Applications

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Oskar Persson; Gustav Persson; [2015]
    Keywords : Polarized band; Magnetoelastic; Torque sensor; Technology and Engineering;

    Abstract : The use of sensors in the automotive industry is increasing, improving performance and safety of the vehicles. The ambition at BorgWarner TorqTransfer Systems AB is to increase torque accuracy to optimize their powertrain solutions.

  4. 43. Train Localization and Speed Estimation Using On-Board Inertial and Magnetic Sensors

    University essay from Linköpings universitet/Reglerteknik; Linköpings universitet/Tekniska fakulteten

    Author : Erik Hedberg; Mikael Hammar; [2015]
    Keywords : signal processing; railway tracks; trains; localization; speed estimation;

    Abstract : Positioning systems for trains are traditionally based on track-side infrastructure, implying costs for both installation and maintenance. A reliable on-board system would therefore be attractive. Sufficient reliability for on-board systems is likely going to require a multi-sensor solution. READ MORE

  5. 44. Angular positioning of a door or window - using a MEMS accelerometer and a magnetometer

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Josefin Voigt; [2015]
    Keywords : Technology and Engineering;

    Abstract : The accurate and reliable detection of opening of doors and windows is vital for home security applications. This master thesis aims to present a way to achieve this using a low-cost and low-power ecompass, containing a MEMS accelerometer and a magnetometer. READ MORE

  6. 45. Characterization of a Zeeman Slower Designed for a 87 Sr Optical Clock

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

    Author : Jonas Olsson; [2015]
    Keywords : metrology; time; frequency; atomic clock; optical clock; strontium; frequency comb; zeeman slower; arduino; Physics and Astronomy;

    Abstract : Optical clocks will potentially become the new frequency standard for the SI-definition of the second. Many national metrology institutes around the world have already implemented different versions of such clocks and others are in process of doing so. At SP Technical Research Institute of Sweden, this process has recently begun. READ MORE
