  1. 21. AVR for a synchronous generator with a six-phase PM alternator and rotating excitation system

    Uppsats för yrkesexamina på avancerad nivå, Elektricitetslära

    Författare :Boris Ivanic; [2013]
    Nyckelord :AVR; automatic voltage regulator; PM; alternator; excitation system;

    Sammanfattning : Automatic voltage regulation is necessary for all power producing synchronous generators to ensure that the produced power have a constant and stable voltage level and to sustain grid stability. The aim of this thesis is to design and build an automatic voltage regulator for a synchronous generator. LÄS MER

  3. 22. Finite States Machine Models for Cell Control Code Generation

    Master-uppsats, KTH/Industriell produktion

    Författare :Xiaofeng Hu; [2012]
    Nyckelord :;

    Sammanfattning : Controlling a manufacturing cell is a complex task to. A manufacturing system could be regarded as a discrete event system from flow and control perspective. However,  it’s a rather intractable to model it analytically for behavior analysis and control development. LÄS MER

  4. 23. Implementering av mjukvarubaserat PLC-system för reglering av magnetiseringen av en synkrongenerator

    Uppsats för yrkesexamina på grundnivå, Elektricitetslära

    Författare :Elias Björkelund de Faire; [2011]
    Nyckelord :PLC; mjukvaru-PLC; magnetisering; generator; vattenkraft;

    Sammanfattning : In order to reduce the price for, and improve the performance of automatic control systems for magnetization of synchronus generators, the possibilities of using a PC based software PLC system, Programmable Logic Controller, has been investigated. The result is a system based on the CoDeSys software PLC with runtime environment from 3S-Software, communicating with external units via Modbus fieldbus. LÄS MER

  5. 24. Controller programming with CoDeSys for an automated timber sorting system

    Uppsats för yrkesexamina på avancerad nivå, Signaler och System

    Författare :Nils Breitholtz; [2010]
    Nyckelord :CoDeSys; CANOpen; Controller programming;

    Sammanfattning : This report describes the development of weight measurement application and transducer positioning for the A Sort prototype that has been developed for automatic grading and sorting of timber. The prototype consists of a transportation system with hydraulic and electrical motors, a measurement system with laser scanners and acoustic measurement equipment and a control program for the automated process with CoDeSys.

  7. 25. Architecture for Diagnostic Platform

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för informationsteknologi

    Författare :Sara Hedfors; [2010]
    Nyckelord :diagnostic platform; diagnostic system; architecture; embedded system; control system;

    Sammanfattning : In order to maximize operating time of an industrial machine and minimize stand-by time, service time and operating costs, a diagnostic system can be a useful tool. Diagnostic systems employ information already available in a machine’s control system (such as control signals, system state, sensor readings and so forth) to perform intelligent fault detection and localisation, and predict future faults and service needs.
