  1. 1. Integration of Computer Vision Methods and Sensor Fusion Technologies for Precision Driving

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : FAIZA ALI; MAKSIMS SVJATOHA; [2021]
    Keywords : ;

    Abstract : Increasing interest in artificial intelligence has given rise to new technologies. This has enabled advanced sensors within fields such as computer vision, which boast increased precision, consistency and lack the accumulation of small errors over time. However, they require increased computing power and are prone to processing delays. READ MORE

    Keywords : statistical; analysis; engine; gearbox; sensor; sensors; rotation; rotational; speed; differential; pressure; performance; characteristics; trueness; precision; accuracy; Hall; inductive; induction; gauge pressure; reference; hysteresis; bias; noise; linearity; non-linearity; DEWESoft; DAQ; wheel; tooth; teeth; absolute; rotary; encoder; matlab; XOR; Gray; binary; LabView; sampling; measurement; measuring; statistisk; analys; motor; växellåda; sensor; sensorer; rotation; rotationell; hastighet; fart; differentiell; tryck; prestanda; karaktäristik; trueness; precision; accuracy; noggrannhet; onoggrannhet; Hall; induktiv; induktion; tryckskillnad; referens; hysteres; bias; avstånd; brus; linjäritet; linearitet; olinear; olinjär; olinearitet; olinjäritet; DEWESoft; DAQ; sampling; mätning; hjul; tand; tänder; absolut; rotationsgivare; givare; matlab; XOR; Gray; binär; LabView;

    Abstract : This thesis provides a standardized method to measure accuracy for engine and gearbox sensors. Accuracy is defined by ISO 5725, which states that trueness and precision need to be known to provide a metric for accuracy. However, obtaining and processing the data required for this is not straight forward. READ MORE

  4. 3. Paddle stirrer to a reverberation chamber

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Andrea Mastrorilli; Josefin Holmgren; [2019]
    Keywords : paddle stirrer; reverberation chamber; control system; encoder; magnetic encoder; paddle-omrörare; modväxlande kammare; styrsystem; sensor; magnetisk sensor;

    Abstract : Halmstad University is currently equipped with an Echo-free chamber to perform EMC testing, but no reverberation chamber. The construction of a paddle stirrer to be utilized in Halmstad University would drastically reduce the time required to perform EMC testing, since reverberation chambers are more efficient than Echo-free chambers for these kind of tests.

  5. 4. 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

  6. 5. Torque Sensor Free Power Assisted Wheelchair

    University essay from Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)

    Author : Jonas Johansson; Daniel Petersson; [2007]
    Keywords : torque sensor free; power assisted wheelchair; velocity disturbance controlled; power assisting; wheelchair; digital control; assisting power; motorized; sensor free; disturbance controlled; intelligent; rotational encoder; rotary encoder; electrical motors; development board; controller card;

    Abstract : A power assisted wheelchair combines human power, which is delivered by the arms through the pushrims, with electrical motors, which are powered by a battery. Today’s electric power assisted wheelchairs use force sensors to measure the torque exerted on the pushrims by the user. READ MORE
