1. 1. Control over the Cloud : Offloading, Elastic Computing, and Predictive Control

   Författare :Per Skarin; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cloud; Control Theory; Model Predictive Control; Offloading; Elastic Computing; Networks; Utility Computing; Cloud Services; Internet-of-Things; Distributed Cloud; 5G Systems;

   Sammanfattning : The thesis studies the use of cloud native software and platforms to implement critical closed loop control. It considers technologies that provide low latency and reliable wireless communication, in terms of edge clouds and massive MIMO, but also approaches industrial IoT and the services of a distributed cloud, as an extension of commercial-of-the-shelf software and systems.

3. 2. Event-Based Control and Estimation with Stochastic Disturbances

   Författare :Toivo Henningsson; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; event-based control; stochastic control; event-based estimation; control over networks; quantized measurements; sporadic control; embedded control;

   Sammanfattning : This thesis deals with event-based control and estimation strategies, motivated by certain bottlenecks in the control loop. Two kinds of implementation constraints are considered: closing one or several control loops over a data network, and sensors that report measurements only as intervals (e.g. with quantization).

4. 3. Stochastic Event-Based Control and Estimation

   Författare :Toivo Henningsson; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; event-based control; event-based estimation; sporadic control; stochastic control; stochastic hybrid systems; sum-of-squares methods; control over networks; quantized measurements;

   Sammanfattning : Digital controllers are traditionally implemented using periodic sampling, computation, and actuation events. As more control systems are implemented to share limited network and CPU bandwidth with other tasks, it is becoming increasingly attractive to use some form of event-based control instead, where precious events are used only when needed.

5. 4. On performance limitations of large-scale networks with distributed feedback control

   Författare :Emma Tegling; Henrik Sandberg; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Networked control systems; microgrids; platooning; vehicular formation; multi-agent systems; H2 norms; fundamental limitations; consensus; Distributed control; large-scale networks; oscillator networks; power networks; power system dynamics; system performance; spatially invariant systems; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : We address the question of performance of large-scale networks with distributed feedback control. We consider networked dynamical systems with single and double integrator dynamics, subject to distributed disturbances. We focus on two types of problems. First, we consider problems modeled over regular lattice structures. LÄS MER

7. 5. Engineered temporary networks : Effects of control and temporality on inter-organizational interaction

   Författare :Carl Kronlid; Enrico Baraldi; Francesco Ciabuschi; Frida Lind; Uppsala universitet; []
   Nyckelord :Inter-organizational networks; inter-organizational interaction; network management; control; temporality; temporary networks; Engineering Science with specialization in industrial engineering and management; Teknisk fysik med inriktning mot industriell teknik;

   Sammanfattning : The world is facing a growing threat of antibiotic resistance. The development of new antibiotics is of utmost importance; otherwise, we go back to the pre-antibiotic era where common infections become life-threatening. Despite this need for new antibiotics, a market failure is hampering its development. LÄS MER
