2. 1. Augmenting the Remote Control : Studies in Complex Information Navigation for Digital TV

   Author : Aseel Berglund; Sture Hägglund; Linköpings universitet; []
   Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; remote control; digital TV; paper-based TV guides; speech interaction; speech interfaces; Computer science; Datavetenskap;

   Abstract : The transition to digital TV is changing the television set into an entertainment as well as information supplier device that provides two-way communication with the viewer. However, the present remote control device is not appropriate for navigation through the huge amount of services and information provided by the future digital TV, presumably also a device for accessing the Internet.

4. 2. Resource-aware Wireless Process Control

   Author : Takuya Iwaki; Karl H. Johansson; Sophie Tarbouriech; KTH; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial process control; Networked control systems; Wireless network; Event-triggered control; Electrical Engineering; Elektro- och systemteknik;

   Abstract : To tackle the ever-growing demands on high-quality and cost-effective industrial production, recent developments in embedded sensing, wireless communication, and cloud computing offer great opportunities. Resource-aware reliable wireless communication and real-time control are needed to leverage these technologies. READ MORE

5. 3. On LQG-Optimal Event-Based Sampling

   Author : Marcus Thelander Andrén; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Event-based control; LQG control; sampled-data control; Stochastic control; Event-based PID control; Event-based state estimation; stochastic triggering;

   Abstract : Event-based control is a promising concept for the design of resource-efficient feedback systems, where events such as sampling, actuation, and data transmissions are triggered reactively based on monitored control performance rather than a periodic timer. In this thesis, we investigate how sampling and communication events should be triggered to fully exploit the potential of event-based control based on the classic linear–quadratic–Gaussian (LQG) framework.

6. 4. Control and Communication with Signal-to-Noise Ratio Constraints

   Author : Erik Johannesson; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Real-time coding; SNR; Causal coding; AWN channel; AWGN channel; Remote source; Networked control; Control over channel; Convex optimization; Wiener filter;

   Abstract : This thesis is about two problems in the intersection of communication and control theory. Their common feature is that they involve communication over an additive white noise channel with a signal-to-noise ratio (SNR) constraint. The first problem concerns the transmission of a real-valued signal from a partially observed Markov source. READ MORE

7. 5. Compensating for Unreliable Communication Links in Networked Control Systems

   Author : Erik Henriksson; Karl Henrik Johansson; Henrik Sandberg; Bruno Sinopoli; KTH; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; networked control; packet loss compensation; unreliable communication; control over wirless networks; Automatic control; Reglerteknik;

   Abstract : Control systems utilizing wireless sensor and actuator networks can be severely affectedby the properties of the communication links. Radio fading and interferencemay cause communication losses and outages in situations when the radio environmentis noisy and low transmission power is desirable. READ MORE
