  2. 16. Backstepping and control allocation with applications to flight control

    Author : Ola Härkegård; Torkel Glad; Marc Bodson; Linköpings universitet; []
    Keywords : backstepping; control allocation; flight control; control theory; nonlinear control; reglerteknik; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : In this thesis we study a number of nonlinear control problems motivated by their appearance in flight control. The results are presented in a general framework and can also be applied to other areas. The two main topics are backstepping and control allocation. READ MORE

  5. 18. Source-channel coding for closed-loop control

    Author : Lei Bao; Mikael Skoglund; Karl Henrik Johansson; Fredrik Gunnarssson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optimal control; joint source--channel coding; source-channel coding; joint coding and control; certainty equivalence; linear quadratic control; stochastic control; wireless sensor network; Telecommunication; Telekommunikation;

    Abstract : Networked embedded control systems are present almost everywhere. A recent trend is to introduce wireless sensor networks in these systems, to take advantage of the added mobility and flexibility offered by wireless solutions. In such networks, the sensor observations are typically quantized and transmitted over noisy links. READ MORE

  6. 19. Development and evaluation of methods for control of multiple-input multiple output systems

    Author : Fredrik Bengtsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hold-input; Unreliable communication links; Decentralized control; MIMO systems.; Delays; LQG control; Input-output scaling; Control configuration selection; Gramian based measures;

    Abstract : In control, the most common type of system is the multiple-input multiple-output (MIMO) system, where the same input may affect multiple outputs, or conversely, the same output is affected by multiple inputs. In this thesis two methods for controlling MIMO systems are examined, namely linear quadratic Gaussian (LQG) control and decentralized control, and some of the difficulties associated with them.

  7. 20. Nonlinear Modeling and Feedback Control of Drug Delivery in Anesthesia

    Author : Margarida M. Silva; Alexander Medvedev; Teresa Mendonça; Torbjörn Wigren; Robain De Keyser; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; anesthesia; drug delivery; feedback control; nonlinear modeling; pharmacokinetics pharmacodynamics; PID control; system identification; Wiener model; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Abstract : General anesthesia is a drug-induced reversible state where neuromuscular blockade (NMB), hypnosis, and analgesia (jointly denoted by depth of anesthesia - DoA) are guaranteed. This thesis concerns mathematical modeling and feedback control of the effect of the muscle relaxants atracurium and rocuronium, the hypnotic propofol, and the analgesic remifentanil. READ MORE
