  4. 23. A Survey and Comparison of Time-Delay Estimation Methods in Linear Systems

    Författare :Svante Björklund; Lennart Ljung; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In this thesis the problem of time-delay estimation (TDE) in linear dynamic systems is treated. The TDE is studied for signal-to-noise ratios, input signals, and systems that are common in process industry. This also implies that both open-loop and closed-loop cases are of interest. LÄS MER

  5. 24. Active Control and Modal Structures in Transitional Shear Flows

    Författare :Onofrio Semeraro; Dan Henningson; Bernd Noack; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flow control; flat-plate boundary layer; optimal controllers; model reduction; turbulent jet; POD; DMD; Koopman modes;

    Sammanfattning : Flow control of transitional shear flows is investigated by means of numerical simulations. The attenuation of three-dimensional wavepackets of Tollmien-Schlichting (TS) and streaks in the boundary layer is obtained using active control in combination with localised sensors and actuators distributed near the rigid wall.

  7. 25. Induction Machine Speed Estimation - Observations on Observers

    Författare :Bo Peterson; Industriell elektroteknik och automation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; control engineering; robotics; Automation; Elektronik och elektroteknik; Electronics and Electrical technology; estimation; sensorless control; observer; induction machine; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : This work focuses on observers estimating flux linkage and speed for induction machines, mainly in the low speed region. With speed estimation, sensorless control is possible, meaning that the speed of induction machines without mechanical speed sensors can be controlled. LÄS MER
