2. 1. Output feedback control : Some methods and applications

   Author : Johannes Nygren; Kristiaan Pelckmans; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

   Abstract : This thesis studies some output feedback control laws. Particularly, iterative learning control (ILC) and decentralized network based algorithms are studied. Applications to control of wastewater treatment plants are outlined. READ MORE

4. 2. The language learning infant: Effects of speech input, vocal output, and feedback

   Author : Lisa Gustavsson; Francisco Lacerda; Roger Moore; Stockholms universitet; []
   Keywords : HUMANIORA; HUMANITIES; human; language; language acquisition; perception; production; humanoid; development; model; embodied system; speech signal processing; vocal tract morphology; acoustic; speech input; information processing; scaling; interaction; growth; infant; imitation; feedback; perceptual salience; modeling; Phonetics; Fonetik; Phonetics; fonetik;

   Abstract : This thesis studies the characteristics of the acoustic signal in speech, especially in speech directed to infants and in infant vocal development, to gain insight on essential aspects of speech processing, speech production and communicative interaction in early language acquisition. Three sets of experimental studies are presented in this thesis. READ MORE

5. 3. Systematic Design of Linear Feedback Amplifiers

   Author : Martin Lantz; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal processing; Volterra series; dynamic distortion; clipping; nonlinear distortion; systematic design; feedback amplifier; Signalbehandling;

   Abstract : This work adds a quantitative description of distortion to the structured design method of negative-feedback amplifiers. It constitutes a power-series representation of the feedback amplifier, which may include dynamic (memory) effects, where the design parameters appear explicitly. READ MORE

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

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

7. 5. On Observer-Based Control of Nonlinear Systems

   Author : Anders Robertsson; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Observers; Output feedback; Separation principle; The Positive Real lemma; Kalman filter; Backstepping; Robotics; Automation; Chained form systems; reglerteknik; robotteknik; Automatiska system; control engineering; Lyapunov stability; Nonlinear systems; State estimation;

   Abstract : Filtering and reconstruction of signals play a fundamental role in modern signal processing, telecommunications, and control theory and are used in numerous applications. The feedback principle is an important concept in control theory. READ MORE
