  3. 3. Estimation-based iterative learning control

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Johanna Wallén; Linköpings universitet.; Linköpings universitet.; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Iterative learning control; estimation; industrial robotics; performance; TECHNOLOGY Information technology Automatic control; TEKNIKVETENSKAP Informationsteknik Reglerteknik;

    Sammanfattning : In many  applications industrial robots perform the same motion  repeatedly. One way of compensating the repetitive part of the error  is by using iterative learning control (ILC). The ILC algorithm  makes use of the measured errors and iteratively calculates a  correction signal that is applied to the system. LÄS MER

  4. 4. Virtual sensing of combustion quality in SI engines using the ion current

    Detta är en avhandling från Göteborg : Chalmers tekniska högskola

    Författare :Nicholas Wickström; Högskolan i Halmstad.; [2004]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Internal Combustion Engines; Spark Ignition; Estimation; Control; Neural Networks; Ion Current; neural networks; spark ignition; ion current; internal combustion engines; control; estimation;

    Sammanfattning : Several virtual sensors for combustion quality in spark ignited internal combustion engines are proposed. The virtual sensors estimate combustion quality based on the ion current signal measured in the center of the combustion chamber. Important properties of these sensors are their cost effective implementation and real-time operation. LÄS MER
