  1. 1. Fundamental Limitations of Distributed Feedback Control in Large-Scale Networks

    Författare :Emma Tegling; Henrik Sandberg; Ali Jadbabaie; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Distributed control; Large-scale systems; networked control; decentralized control; fundamental limitations; networked systems; frequency control; smart grid; consensus; spatial invariance; power system dynamics; microgrids; vehicular formation systems; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Networked systems accomplish global behaviors through local feedback interactions. The purpose of a distributed control design is to select interaction rules and control protocols that achieve desired global control objectives. LÄS MER

  3. 2. On H-infinity Control and Large-Scale Systems

    Författare :Carolina Bergeling; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; H-infinity Control; Decentralized Control; Large-Scale Systems; Infinite-Dimensional Systems;

    Sammanfattning : In this thesis, a class of linear time-invariant systems is identified for which a particular type of H-infinity optimal control problem can be solved explicitly. It follows that the synthesized controller can be given on a simple explicit form. LÄS MER

  4. 3. Asynchronous Algorithms for Large-Scale Optimization : Analysis and Implementation

    Författare :Arda Aytekin; Mikael Johansson; Panagiotis K. Patrinos; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; convex optimization; optimization; asynchronous algorithms; algorithms; parallel algorithms; large-scale; big data; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : This thesis proposes and analyzes several first-order methods for convex optimization, designed for parallel implementation in shared and distributed memory architectures. The theoretical focus is on designing algorithms that can run asynchronously, allowing computing nodes to execute their tasks with stale information without jeopardizing convergence to the optimal solution.

  5. 4. Gradient Methods for Large-Scale and Distributed Linear Quadratic Control

    Författare :Karl Mårtensson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Large-Scale Control; Distributed Control; Linear Quadratic Gaussian Control; Gradient method; Controller Synthesis;

    Sammanfattning : This thesis considers methods for synthesis of linear quadratic controllers for large-scale, interconnected systems. Conventional methods that solve the linear quadratic control problem are only applicable to systems with moderate size, due to the rapid increase in both computational time and memory requirements as the system size increases.

  7. 5. Storskaligt kreativt samarbete : Organisering och kollektivt lärande i ett konst- och teaterprojekt

    Författare :Aron Schoug; Tore West; Staffan Nilsson; Jon Ohlsson; Peter E Johansson; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Large-scale collaborative creativity; collective learning; organizing; organizational learning; artistic collaboration; theater production; ethnography; leadership; Storskaligt kreativt samarbete; kollektivt lärande; organisering; organisatoriskt lärande; konstnärligt samarbete; teaterproduktion; etnografi; ledarskap; pedagogik; Education;

    Sammanfattning : Storskaliga kreativa samarbeten blir allt vanligare i dagens organisationer, till exempel inom kreativa näringar, innovationsprocesser och utvecklingsprojekt. I sådana samarbeten behöver många individer vara kreativa och deras bidrag sammanflätas. LÄS MER
