    Abstract : This doctoral thesis treats three issues in control engineering related to relay feedback and multivariable control systems. Linear systems with relay feedback is the first topic. Such systems are shown to exhibit several interesting behaviors. READ MORE

  2. 2. Feedback control of cerebellar learning

    University dissertation from Associative Learning

    Author : Anders Rasmussen; [2014]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Motor learning; Rescorla-Wagner; Anticipation; In vivo Electrophysiology; Purkinje cells; Nucleo-Olivary inhibition; Inferior Olive; Classical Conditioning; Eyeblink Conditioning; Feedback;

    Abstract : The ability to anticipate future events and to modify erroneous anticipatory actions is crucial for the survival of any organism. Both theoretical and empirical lines of evidence implicate the cerebellum in this ability. It is often suggested that the cerebellum acquires “expectations” or “internal models”. READ MORE

  4. 4. Limited Feedback Information in Wireless Communications Transmission Schemes and Performance Bounds

    University dissertation from Stockholm : KTH

    Author : Thanh Tùng Kim; Mikael Skoglund; Hesham El Gamal; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diversity-multiplexing tradeoff; Large deviation analysis; Limited feedback; MIMO channels; Relay channels; TECHNOLOGY Information technology Telecommunication; TEKNIKVETENSKAP Informationsteknik Telekommunikation;

    Abstract : This thesis studies some fundamental aspects of wireless systems with partial channel state information at the transmitter (CSIT), with a special emphasis on the high signal-to-noise ratio (SNR) regime. The first contribution is a study on multi-layer variable-rate communication systems with quantized feedback, where the expected rate is chosen as the performance measure. READ MORE

  5. 5. Automatic Tuning of PID Controllers Based on Asymmetric Relay Feedback

    University dissertation from Department of Automatic Control, Lund Institute of Technology, Lund University

    Author : Josefin Berner; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis presents an improved version of the classic relay autotuner. The proposed autotuner uses an asymmetric relay function to better excite the process in the experiment phase. The improved excitation provides the possibility to obtain better models and hence better tuning, without making the autotuner more complicated or time consuming. READ MORE
