  1. 1. Source-channel coding for closed-loop control

    Författare :Lei Bao; Mikael Skoglund; Karl Henrik Johansson; Fredrik Gunnarssson; KTH; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
