  1. 1. Incremental and Hierarchical Deadlock-Free Control of Discrete Event Systems with Variables: A Symbolic and Inductive Approach

    Författare :Mohammad Reza Shoaei; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Discrete event systems; IC3; large-scale systems; model checking; incremental control; supervisory control; hierarchical control; maximal permissiveness;

    Sammanfattning : Today's industry trend towards agile product development cycles and the ambition to shorten the time-to-market, represents an extremely competitive marketplace. This has driven the industry to use very complex and highly flexible manufacturing systems. LÄS MER

  3. 2. 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.

  4. 3. Coordination, Consensus and Communication in Multi-robot Control Systems

    Författare :Alberto Speranzon; Karl Henrik Johansson; George J. Pappas; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multi-robot Coordination; Intelligent Control; Control under Communication Constraints; Automatic control; Reglerteknik;

    Sammanfattning : Analysis, design and implementation of cooperative control strategies for multi-robot systems under communication constraints is the topic of this thesis. Motivated by a rapidly growing number of applications with networked robots and other vehicles, fundamental limits on the achievable collaborative behavior are studied for large teams of autonomous agents.

  5. 4. Fuel-efficient and safe heavy-duty vehicle platooning through look-ahead control

    Författare :Valerio Turri; Karl H. Johansson; Nathan van de Wouw; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; platooning; eco-driving; look-ahead control; dynamic programming; distributed model predictive control; optimal control; autonomous vehicles; Electrical Engineering; Elektro- och systemteknik; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : The operation of groups of heavy-duty vehicles at small inter-vehicular distances, known as platoons, lowers the overall aerodynamic drag and, therefore, reduces fuel consumption and greenhouse gas emissions. Experimental tests conducted on a flat road and without traffic have shown that platooning has the potential to reduce the fuel consumption up to 10%. LÄS MER

  7. 5. Hierarchical Control and Restart of Flexible Manufacturing Systems

    Författare :Kristin Andersson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Restart; Flexible manufacturing; Finite state automata; Petri nets; Supervisory control theory; Process algebra; Discrete event systems; Hierarchical control; Supervisor synthesis;

    Sammanfattning : Product life-cycles are constantly shortening, and the amount of new product types increases, for example in the automotive industry. Growing demands on flexibility and ability to decrease time to market has made it increasingly important to find methods for fast and accurate development of control programs for flexible manufacturing cells.
