  1. 16. Performance Analysis of Positive Systems and Optimization Algorithms with Time-delays

    Författare :Hamid Reza Feyzmahdavian; Mikael Johansson; Peter Richtarik; KTH; []
    Nyckelord :Optimization; Delay; Positive system; Asynchronous; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Time-delay dynamical systems are used to model many real-world engineering systems, where the future evolution of a system depends not only on current states but also on the history of states. For this reason, the study of stability and control of time-delay systems is of theoretical and practical importance. LÄS MER

  3. 17. Methods for Automated Design of Fault Detection and Isolation Systems with Automotive Applications

    Författare :Carl Svärd; Mattias Nyberg; Erik Frisk; Mattias Krysander; Vincent Cocquempot; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Fault detection and isolation (FDI) is essential for dependability of complex technical systems. One important application area is automotive systems, where precise and robust FDI is necessary in order to maintain low exhaust emissions, high vehicle up-time, high vehicle safety, and efficent repair.

  4. 18. Distributed Optimization and Control : Primal--Dual, Online, and Event-Triggered Algorithms

    Författare :Xinlei Yi; Karl H. Johansson; Dimos V. Dimarogonas; John S. Baras; Antonis Papachristodoulou; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Distributed nonconvex optimization; distributed online convex optimization; distributed event-triggered control; primal-dual algorithm; stochastic gradient descent; zeroth-order algorithm; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : In distributed optimization and control, each network node performs local computation based on its own information and information received from its neighbors through a communication network to achieve a global objective. Although many distributed optimization and control algorithms have been proposed, core theoretical problems with important practical relevance remain. LÄS MER

  5. 19. Channel Prediction Based On Sinusoidal Modeling

    Författare :Ming Chen; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Long range channel prediction is considered as one of the most important enabling technologies to future wireless communication systems. The prediction of Rayleigh fading channels is studied in the frame of sinusoidal modeling in this thesis. A stochastic sinusoidal model to represent Rayleigh fading channel is proposed. LÄS MER

  7. 20. Planning and Operation of Demand-Side Flexibility

    Författare :Meng Song; Mikael Amelin; Alessandra Parisio; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Power systems are changing with growing penetration of non-dispatchable renewable generation and increased demand of electric energy. More generation, transmission or distribution capacities are needed to balance the varying production and higher consumption. Demand-side flexibility is a potential solutionto tackle those challenges. LÄS MER
