  1. 1. Development of an exercise machine for enhanced eccentric training of the muscles : A study of sensors and system performance

    Master-uppsats, KTH/Mekatronik

    Författare :Natalija Zivanovic; [2020]
    Nyckelord :Sensor resolution; sample time; smart exercise machine; system performance; incremental encoder; eccentric training; Sensorupplösning; samplingstid; smart träningsmaskin; systemprestanda; inkrementell pulsgivare; excentrisk träning;

    Sammanfattning : Currently, there are various training machines that can support training of the muscles while the muscles are lengthened, also known as eccentric training. Training machines that are widely used to train the muscles eccentrically utilize a flywheel to generate load to the user. LÄS MER

  3. 2. The modernization of a DOS-basedtime critical solar cell LBICmeasurement system.

    Master-uppsats, Karlstads universitet

    Författare :Gunnar Hjern; [2019]
    Nyckelord :Pascal programming language; Linux; operating system; real-time; PREEMPT_RT patch; Free Pascal compiler; Lazarus; multi-threading; computer controlled measurements; false color map; refactoring; software modernization; adaptation layer; MS-DOS; GPIB; IEEE-488; silicon solar cell; quantum efficiency; LBIC; electron recombination; serial communication; micro-controller; ISR; incremental encoder; lock-in amplifier; trans-impedance amplifier; triggered measurement;

    Sammanfattning : LBIC is a technique for scanning the local quantum efficiency of solar cells. This kind of measurements needs a highly specialized, and time critical controlling software. In 1996 the client, professor Markus Rinio, constructed an LBIC system, and wrote the controlling software as a Turbo-Pascal 7.0 application, running under the MS-DOS 6. LÄS MER

  4. 3. Analysis of Velocity Estimation Methods for High-Performance Motion Control Systems

    Master-uppsats, KTH/Reglerteknik

    Författare :Ruth Aleksandrauskaite; [2018]
    Nyckelord :;

    Sammanfattning : The majority of all commercial electronics hardware is manufactured usingSurface Mount Technology (SMT). Nevertheless, the increased complexityand miniaturization of electronics impose tough performance requirementson the automation process. LÄS MER

  5. 4. Dimensionsmätare : En PLC-baserad mätmetod för att bestämma en brädas dimension

    Uppsats för yrkesexamina på grundnivå, Mittuniversitetet/Avdelningen för elektronikkonstruktion

    Författare :Ludvig Svensson; [2017]
    Nyckelord :PLC; HMI; Encoder; Distance Sensor; Thickness; Width; Styrsystem; människa-maskin-gränssnitt; pulsgivare; avståndssensor; tjocklek; bredd;

    Sammanfattning : I det här projektet har ett mätsystem utvecklats för dimensionsmätning av brädor. Mätsystemet består av ett programmerbart styrsystem (PLC), ett människa-maskin-gränssnitt (HMI), en pulsgivare för breddmätning samt två avståndssensorer för tjockleksmätning. LÄS MER

  7. 5. Design and optimization of a signal converter for incremental encoders : A study about maximizing the boundary limits of quadrature pulse conversion

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :ANTON DAHLQVIST; Victor Karlsson; [2016]
    Nyckelord :;

    Sammanfattning : This project was carried out during spring 2016 in collaboration with BOSCH Rexroth, Mellansel, and aimed to investigate the possibility of implementing a converter with the ability to scale incremental pulse resolution and also convert the velocity to a 4-20mA current loop reference. An investigation on how a fault tolerance mechanism could be implemented to increase the dependability of the encoder was done and the out-coming results were implemented. LÄS MER
