  4. 4. Estimation-based iterative learning control

    Författare :Johanna Wallén; Mikael Norrlöf; Svante Gunnarsson; Jian-Xin Xu; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Iterative learning control; estimation; industrial robotics; performance; Automatic control; 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

  5. 5. Virtual Sensing of Combustion Quality in SI Engines using the Ion Current

    Författare :Nicholas Wickström; Bertil Svensson; Gerard W. Malaczynski; Chalmers University of Technology; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; neural networks; spark ignition; ion current; internal combustion engines; control; estimation; Internal Combustion Engines; Spark Ignition; Estimation; Control; Neural Networks; Ion Current;

    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
